Cwlondon, the Linn LP12 is a "finicky" table, which requires specific knowledge to set up properly. I can understand if you had a frustrating experience with it. I, however, am a factory trained Linn setup technician, and had no trouble at all keeping my LP12 in top operation order.
For those with similar experiences to Cwlondon, perhaps a simple direct drive table might be a good choice, or even some other more easily set up belt drive tables. You'll find that an unsuspended TT is much easier to set up, regardless of drive system used.
I don't mean to sound harsh about my assessments of these tables. I just want to provide some perspective about the various levels of performance available from certain designs and implementations.
