Quiet,cheap table: under $500 new or used....

DUAL cs 5000 $300 I was one on audioweb

Go with a Rega P2 or P3. I bought my Planar 3 w/ Rega Elys cartridge on Audiogon for $500.00. I'm very pleased with my decision. I also plan on upgrading via replacing the glass platter
with an acrylic platter. I also plan on purchasing the Heavyweight
tonearm tweak, ect...The Absolute Sound's latest issue has an article describing the upgrading path
that is possible with Rega turntables. MusicDirect is currently
advertising all of them. Definitely, take a look at the article or check
out Music Direct's website. Also, when you buy a Rega turntable,
especially the Planar 3, your also buying one of the best tonearms
as well. That being the RB-250 or RB-300, which can be further modified as funds permit. Hope this is helpful.

If you need quiet reliable table you should consider Technics SL-1200. It would last forever, it is simple and fully adjustable.

You could find a Rega Planar 3 in that range.

Or a AR-Es 1
