I have owned a TD-166MkII since I bought it new in 1984. It has always sounded fine to me, and has been very reliable. I bought it when i thought turntables would become extinct, and I refused to re-purchase all of my vinyl in CD form. Who knew vinyl would have such staying power? Anyway, I wouldn't classify any Thorens as a "lemon." They are very well made and designed. The TD-126 MkII is no exception. I have the stock arm with two wands. One has an Ortofon OM-30 Super MM cartridge, and the other a Denon DL-160 HOMC cartridge. They both sound great and track beautifully, with the Denon sounding a bit smoother and richer in my system. Years ago, I had a Grado in it. Not sure why I switched it out, it was a long time ago.
There are many tweaks and mods for vintage Thorens 'tables. I just had a local modder, K-Works in Clifton, New Jersey, do some work on my TD-166MkII. I had new feet installed that provide better damping and leveling ability, added a lot of vibration damping to the plinth and platter, added an Ersa-Mat (I think TTVJ or Needle Doctor sells this item), and upgraded the RCA cables. Too early for a full evaluation, but improvements seem to be subtle, but noticeable, including better bass definition and perhaps a smoother presence range.
Don't let what the shop guy said bother you. Either he wants to sell you a new 'table or he doesn't know much about Thorens decks. Do a web search. There are many sites devoted to vintage Thorens 'tables. Enjoy!
