A few years ago I bought a GP32 from gbax and was very pleased with it, especially as it was the first handheld I had owned and its ability to play some of my favourite 8 + 16 bit classics but I did feel emulation was never really good enough to call perfect and it has gathered a lot of dust...
I've been following the scene for a while but have only just taken the plunge and bought myself a GP32 BLU, looking forward to AtariSt, Genesis, PC Engine, Speccy and C64 emulation and of course Doom
