If you can afford it, I'd recommend the deluxe version. One problem we've found with Cheapass games is that the cardstock is basically a grease-magnet, which is a problem in a proper card-game setting (beer, fritos, and dip). The cheap cards do tend to get grease-stained, but the deluxe cards are made out of coated stuff that does much better.
In any case, I'll probably be dragging 'em up to the GDC just in case. You just never know when a card game will break out during a conference :)
