Ultra and others, how would you rate the Sega systems ?

I would go :

1) Sega Genesis Model 1 (Revisions VA3 to VA6 sound best) + Sega CD Model 1 + 32 X Revision 2 and other variations (CDX, X Eye, Homemade Neptunes, Nomad etc).

Just so you guys know once my Genesis Model 1, 32x, Sega CD and maybe Game Gear all in 1 box is done I'll post video for it.

2) DC (SDISOs ftw)
Saturn

Yes a tie ha

4) Master System/Mark III/Game Gear (Basically they are same anyway)

5) SG1000
