dcRawley is correct, the Fiskars is great. I bought one at a local COSTCO discount store for less than 30 bucks and they are a marvel. Aside from the quality of the cutting, they have consumeable parts - blades and cutting edges that can be replced when worn out to continuously provide quality cuts.
dc, I didn't know they have a scoring blade since I too need to create my own cards and that comes in handy. Thanks.
