turntable/cartridge for old 50's 60's rock records.

While I don't share your generalization of reissued and/or remastered LPs I do enjoy collecting vintage pressings. I suggest a high quality record cleaner then consider the deck. A good cleaning of a new reissue can be surprising. 

there are some used Avengers on Audiomart I'd take a look at if your budget was under $10k.   Not sure what you're looking for being your post was a little older.  Best of luck.

A  AT-95 is just the ticket , made for this music and all you need .
