Jon, sorry to hear about your grief with the NAS. Personally i'd only buy a used TT from a dealer (in person, not online). E-Bay would be a big no no for me.
Re eBay, my first "win" there was an MF MVT pre, i had been after one for years knowing it had a very good phono stage, it turned up and i went straight inside for the usual check over and hoover out, its original phono stage was gone, and in its place something from a cheap integrated, being my first deal on eBay i was raging, but never got anywhere with eBay`s dispute dept and ended up sending it in for a rebuild, and swallowed, it almost put me off for good, but since then i have had no problems whatsoever in over 275 deals, in fact i eventually sold the MVT there and replaced it with a mint MVX.Jon, sorry to hear about your grief with the NAS.
