Take a look at the Pink Fish Media Forum which features many Naim/Linn fans. The usual suspects are the TW Akustik Raven One, the DPS turntable, and the Spacedeck. I own a DPS and like the Spacedeck (at the lower price). Both are excellent tables. The Raven would be difficult to get in you price range though.
Also, having owned a Thorens TD150 (mini-Linn) I don't think that the LP12 is difficult to set up. If this is your only concern, I would try teaching myself.
