I would not buy from gamedoctorhk.com, I just got my gt modded with the lcd, region and av out, and when I used their psu the picture on the tv was all fuzzy and when I tried to press run it resets itself like it would when you press run+select, cheap and nasty rubbish. When I used batteries and a universal psu it works fine. A few years ago I bought a IFU 30+ CD ROM2+ PC Engine and he said that it was all perfect and the thing would not even power up and the condition was garbage when it was stated as 90-95% new and it was a hassle to get a refund.
