^ If the ratchet was well-taken care of, it shouldn't really matter a great deal if it's new or used. Grit and lack of lubrication will do them in pretty quickly. Not that difficult to see the tell-tale signs in the photos posted on Ebay.
Other than Snap-on, Blue-Point, Mac, Matco, or Cornwell, you should be able to find an excellent American-made premium ratchet on Ebay for:
1/4" drive - just under or right about $20 including shipping
3/8" drive - about the same (incl. shipping)
1/2" drive - figure $20 - $26 (incl. shipping)
Only ones I've paid more for were really hard to find collector models that generate bidding wars: #2875 Indestro, #2880 Indestro, and the old =V= Craftsmans with the "flying V" (butterfly) selector.
I'm damn picky about what I post here in this thread. If it's not something I would pay for and use, I ain't gonna post it: beat to hell, rusty, hammered, peeling chrome, engraved: deal-killers. period. too many other options out there, and tomorrow there will be another mess of 'em listed.
added some notes to a few below for you:
