Need help buying a used turntable for $500


OK gang,
My father has left me a vintage collection of Jazz albums and I have my own collection of 70 & 80's Rock music. I have a Denon 3802 receiver which is only sending 110w per channel to a pair of B & W 604 towers. So I am looking for a turntable I can afford and still get the best possible sound.

I have been looking at used Thorens, Rega, Project, & Lencos but it is impossible to tell what model and year are a good value. Can anyone help suggest the criteria I should use for selecting a suitable turnable and offer some models to pursue?

I would greatly appreciate your advise.
Thanks

Can't go wrong with a new Technics and you can add upgrades as budget allows, if you so desire.

Another vote for the Technics. At $399 its build quality, speed consistency, and durability is stupid good for the money. I think it's particularly good for the kinds of music you'll be playing--jazz and classic rock. It shines in bottom end drive and also with acoustic instruments.

Mine's exemplary on things like Bowie's "Let's Dance," anything from the Police, Cars, Elvis Costello, Steve Miller, and also Dave Brubeck, MJQ, John Abercrombie, Gary Burton, Pat Metheny.
