If spending $18,000 on a B9 replica did not compute for you, you may want to point your ionic directional probes to eBay and bid for the custom-built bot from 1965's Lost in Space. It's full size, lights up and has built-in radio CD. And looks good in the gallery after the jump.
Now, if it says "my micromechanism thanks you, my computer tapes thank you and I thank you" after inserting a David Bowie album or "I cannot accept that course of action" when you try something by Christina Aguilera, I'm there. Bidding starts at $1,295.
