I resurrected this old thread just to point out that
woot.com is having a nice deal today and today only on USB turntables. It's $49.99 plus $5 shipping and handling.
If you have a stack of old vinyl LPs kicking around and you want to get them into digital format, I doubt you will have a better opportunity than this sale at woot. [shill] Order now. [/shill]
Download Audacity for free [reviewed a few posts above], and you can make mp3s or CDs with that turntable.
This turntable looks kind of cheap, but it should do the job.
