Got my Sega Saturn USB game pad from Play-Asia the other day and it is by far one of the most comfortable pads I've used.
It's lightweight, responsive and is easy to install and use (just plug into your USB port and play). I've already tested it on some games - Guilty Gear XX #RELOAD, Blazing Star, Progear no Arashi and others and the games responded very well with the pad.
The thing people may complain about is the USB cable being only 200cm long, which may seem too short for some, but it's enough for me (as 2 USB ports are in front of the tower case on one PC and the other has an USB extension cord). Also, the gamepad only uses USB 1.0 connectivity, which may or may not cause some delayed actions, but I have yet to come across any.
In any case, it's an excellent piece of hardware and I highly recommend it. Get one now before stocks run out!
