I'm definitely doing this - actually, to an extreme: the final plan is to print on common card-stock and sleeve the cards in nicer-than-average sleeves. I could afford to do it a more professional way, but I really want the game to grow and for other people to try making cards. :) I'm buying 1500 sleeves for 2 Resource/Victory sets and then one set of each card + a bunch of spare. But, as that's enough for about 75 non-base cards types, and I'm only making 24 this round, the hope is for the collection to grow!
