Looking for approximate prices on systems & accessories

[Vectorman0]

Genesis 3 system - Complete in box, mint, (missing a couple twist ties, has everything else)
Gameboy Tetris Bundle - Complete in box, mint (has everything except for maybe a baggie or two)
NES Action set - Complete in box, very good condition
Retroduo - New
PSone system with modchip, official LCD, video & power cables & white dual shock
Guitar Hero II PS2 Bundle - Complete in box, mint
Atari Light pen CX75 - boxed, good condition

I'm just looking for fair asking prices if I were to sell these here on the forums.

I had trouble getting rid of a pretty mint CIB genesis 3 for $35. Personally I think they are quite cool and should be worth at least $50, but I don't get to decide.

The Guitar Hero 2 bundle is probably only around $20.
