The Sinclair ZX Spectrum 128, the vastly upgraded Speccy with the lovely heatsink on the side, is by far the most beautiful 8-bit micro you could wish for. It's also relatively rare (as it was swiftly substituted by Amstrad's Spectrum +2), but if you're willing to go for an untested machine you could grab one for cheap. Take this ZX Spectrum 128 auction for example. The computer lacks power supply and RF cable and is thus untested, but remains in excellent cosmetic condition. Chances are the thing will work.
