What a great idea!
I bought DH a retro PSP and some games for his birthday recently, and he loved it. He was mad about his PSP when he was younger and I found the console he used to have. I've ordered him some games for his Christmas stocking. DCs are loving it too.
A friend recommended them to me, they're a very small family run business with great customer service.
