Dilemma: New Or Used Old Zenith?

[colortrakker]

The new store I discovered today had a neat surprise: a brand-new, never-before-sold vintage Zenith TV! It was a 19" System 3 table set in a wood cabinet (REAL wood!) with not only Space Command, but Space Phone. I date it from about the early '80s. The lady at the store (owner's wife, I think) told me they never sold it when it was new, and it's been sitting in the store, longing for an owner, ever since. The registration card and plastic wrap are still attached to the back of the set. They're asking $100, which is kinda rich for me, but there's a used System 3 there that's very similar. It's got Zoom instead of Space Phone but it's pretty much the same set otherwise, and it's only $20 (original remote included!). I imagine they're both built like tanks and have the weight to match, with the wood and everything.

If we were each other, and had a buck to burn, which would set you go for?
