I've played a lot of densha de go recently (and some other train games in the same style, like JP train sim games on 3DS) and want to get a controller and play some of the PS1/PS2 era games. I've got a softmod PS2 I can play JP region games on, I'd rather have a two handle controller (I just think they're cooler), and I'd prefer a USB one since it would be useful in other places, but would be alright with something using the PlayStation controller port if necessary. What controllers should I look out for, and where should I look for them?
