In the market for a dance pad

[booty]

Ok, I know theres like 30 posts on people asking which pads are the best.. and I read all of them that I could find.. but to those of you with pads can you please be a bit more specific with the pros and cons of your pads.. I'm thinking I'll buy a pad and it wont be compatible or I'll think it comes with a ps2-usb converter and it wont.. something.. So please give me a little review on what kind of pad you have, if it comes with converter, if its completly compatible with stepmania, anything information you think would be useful.. it's for my birthday so money wise I'm not too worried cause if they wont buy it ill make them give me cash and I'll go buy it myself.. I dont want to buy a whole machine but I can spend a few hundred if it's going to be worth every penny of it.. Thanks

-edit-

the one ive been looking at the most is the Cobalt Flux for $300
im just wondering if its worth the money..
and I'm wondering if I need some kind of special adapter for it to work on my PC?
and is it compatible with SM?
