practicality

Okay, so I'm giving in, as Anthony is bringing his PSOne in for me, because he's a sweetheart and we love him, and I want to get better at DDR, but arcade = expensive and not nearby. PSX imports are kind of out of the question, as it's not modded already, and it's sort of not mine, although if I could figure out a way to get my hands on the X fighting game, I'd consider talking Anthony into it. Which leaves the three USA DDR releases - DDR, Konamix, and Disney mix, and as I don't like Disney quite that much, it's down to DDR and DDR Konamix, both of which I can get.

Now, Konamix is $10 cheaper, but...can anybody offer a comparasion between the two before I shell out thirty or forty bucks? Or are you all perfectly happy with your little expensive PS2s that I can't afford, leaving me to hope for the best on my own ^^?
