It's a self-sharpening blade and has a good sturdy metal base. You probably wouldn't want to tote the thing around with you but it's great for a cutter you have on your work table.
I shopped around and got a decent price on eBay, there are a couple on US eBay at the moment at around a hundred bucks which probably gives you a ballpark price if you're comparing stuff.
There's a little YouTube demo here
I, too, have the 12" Dahle. The grid has almost totally worn off the center, so I looked into replacing it with the 15", but it is just a bit too big for my area. However, I really love the cutter and use it for all my cards. Have had it for at least 13 years, so it really lasts. The price isn't too bad, in my opinion for how long it lasts without having to replace parts.
