First used turntable +- $20,000. Any suggestions?

I second the micro seiki but admit my bias is toward vacuum tables. Johan at highend broker (right here on a-gon) also has a great selection of cartridges at great prices. As Raul points out dont forget a good match with step up (if needed) and preamp is critical to maximizing your investment. Take your time there are a lot of great deals here on a-gon and even more opinions.

If you do your homework you can minimize the risk of buying used. I have purchased over 20 used tables among them some of the very high end with a minimum of problems and due to the lower cost easily covered the few problems I ran into (isnt buying used why were on agon?) Part of the joy of analog is dialing in your own gear, It isnt that complicated and its the only way to maximize your investment. Play with your setup (when you get it) and listen your ears will tell you whats up. There are many good guides and of course the forums. Fremers dvd is a good general guide that you should look at now before you buy to familiarize yourself with the process. If I didnt do my own set ups I wouldnt own a TT in the first place. Its not magic as many would have you believe. If you can get a seller to give you an evaluation period that would be great but dont pass up a great deal because you dont think you can do the setup. The learning process is integral to the experience of owning and enjoying a fine turntable. If you can find George Merrills guide (I think you can still get it from him) that has a lot of good info in it. Enjoy the whole hobby!
