tbh, I'm looking at picking up a deck, but it's more for the artistic value than their quality. even if they're going for over 10 bucks (not much more, but a little over), I'd still consider that a negligible expense. And supposedly there's only 1,100 decks floating around, so worst case scenario, I can auction them off later.
But yeah, I'm fully aware that they won't make me any better, I just like the look of them. I don't see a problem with buying a deck or two because I like how they look.
