I thought the GBPlayer was still $50...
Anywhoo, naw, I already have the GBPlayer... (if you look at that picture, you can tell by looking in the top, right hand corner...)
I got the PSone LCD combo basically for the LCD screen (although there are some PS1 games I'm going to get now...) and was playing around with it last night, hooking it up to my DVD player and various other systems... Having the PSone playing a GBA game using the Gamecube with an SNES style controller amused me a lot.

('eh, so I'm easily amused, what can I say?)
