Loved my XBMC - it's in the loft but waiting to come out at the new house if I can get a games room squeezed in somewhere!!
My father has one that I got him as a gift and he never used, he may part with it - what's the going rate for them these days? I'll drop him a call later.
These ones have a load of SNES/NES/Megadrive ROMS loaded too....
