There's a couple of reviews on audioasylum.
I started a similar thread on another audio board with regard to my P3 and the concensus was that the P3 is engineered to a price point, and the table is difficult to substantially improve without investing money sufficient to have just bought a new table.
My main problem with the P3 is speed stability. Apparently the best way to improve that is to have a new pulley manufactured that can accomodate two belts and forego 45rpm playback. Such a pulley is not commercially available so you'll need a friend in the machining business.
The arm is a different matter.
