WOW! Are you as excited as you SHOULD be?!? The Carl is all that and a bag of chips... I cut 13 sheets of Stampin' Up! Cardstock in my Carl at one time. It is a MUST HAVE machine for crafters who need to cut multiple sheets for swap preps, invitations... any bulk preparations. There is a tiny catch...
First off; this is not a CHEAP product. The Heavy Duty Cutters retail on average for (US) $80-120. Keep in mind however that it WILL last you forever. You will never need to buy another Heavy Duty cutter for as long as you LIVE. Note the lifetime warranty. Products purchased from ANY seller can be returned to Carl directly.
Second; there is a bit of a learning curve. Take a look at the picture above... See that bar the paper is butted up against? It is NOT Necessarily a 90 degree angle. It is a removable, magnetic, sliding bar designed to aid you in your alignment. It does have a tendency to wobble and move if you push a stack of paper against it with too much force.

I suggest that along with the purchase of your Heavy Duty Carl you get yourself an affordable metal or acrylic angle/triangle like this one... Be sure it is 12" tall if you have a 12" trimmer... 15" tall if you have a 15" trimmer. You can use this right angle to align your Carl's Magnetic bar when you are not cutting on the even inch lines (the even inch measurements are already marked with a straight line you can align the magnetic bar against.) After the bar is in place you can gently butt your stack of cardstock up to the bar. At this point you would lock the cutting rail and blade down. The paper is held very snugly by the cutting rail. Cut the paper by sliding the rotary knob up and down; typically 4-5 passes for a full stack of cardstock.
The grid lines can be troublesome for some. Users have commented that the 210 model only shows top and bottom measurements up to 11 1/2". But if you look at the picture above you will see that the last line on the grid, at the left is very bold... it is the 12" line. Now if you were cutting a slice at the 11 3/4" mark... well then OK... you might be frustrated. It's never been an issue for me. I should note; unlike my Fiskars personal trimmer and other trimmers I have tried; I have never experienced ANYTHING BUT perfect accuracy in measurement with my Carl.
The Blades are very sharp; but it is almost impossible to cut yourself with this trimmer as they are well covered and guarded. Carl also sells scoring and perforating blades for this model; though I have never used them. You can get a lot of life out of your blade; I have had to change mine twice in 2 years... but the mats the blades run on need to be rotated and flipped over regularly. It is easy to tell when the mats are "spent" and I have found I go through about 2 mats per blade.
The cuts produced by this cutter are PERFECT. No flaws, curves or frays. This of course is dependent on using the product correctly. This means installing the blade according to the manufacturer instructions and aligning the magnetic bar to a 90 degree angle.
To address some issues others have mentioned with various rotary trimmers; what's nice about the Carl is that the spot where the blade hits the paper is visible and not obstructed by the cutting rail/rotary knob. I can SEE what I am doing. I think the other key to the Carl Cutter's ease of use is the locking cutting rail. The paper you are cutting isn't going anywhere. No slippin' and sliddin'. Plus you can cut acetate, chipboard, cardboard and very heavy papers with the Carl... and it will cut them like buttah!
Negatives: you won't be bringing this to your crops... I like to use my Fiskars Personal Trimmer (similar to the euro trimmer reviewed earlier) for crops and my "one-card-at-a-time" projects. When I need to cut paper for 3-100 projects; my Carl is what I use. I use the 12" model; but others prefer the 15" because they like the ability to cut 12x12 paper on an angle. Anything larger is frivolous for the average crafter.

Be sure to note; the product described is NOT the same as the Carl Cutter "professional" series; available retail (us) $15-40. The Professional series (pictured at left) does NOT have a locking cutting bar, or an alignment bar. It also can only cut 3-5 sheets of cardstock. It is the professional series that you may have seen at Sams Club or Costco... it's is NOT the Carl Cutter touted by professional papercrafters. Look for the words "Heavy Duty", and product codes on the cutter; DC-210/220/238/250. I will say that many have been pleased with the other products in the Carl Line... I however cannot attest to their use or reliability.
Best prices? Most people are saying Ebay right now; expect to pay about (US)$100. Anything less is probably a GREAT deal. Remember that Carl has that Limited Warranty... so if you have any problems with your purchase; be sure to call them! Look
