Rega RP10 or Nottingham Space 294 or VPI Prime


I am moving up from a Rega P5 which I've enjoyed for nearly 10 years (with a Benz Glider). I would appreciate any comments if you've actually owned or spent time with any of the above tables, and also comments on cartridges used with them. The Rega usually comes with the Apheta. Yes, I know, there are other choices, but due to location of dealers and the fact that there is limited time available to any of us in this lifetime, I've narrowed it down to these three choices. I also considered TW Acustic Raven, but they are in a higher price bracket and there are no area dealers.

Former planar 3 owner, now have an LP12 for the last 18 yrs.

i recently heard the Prime with a Grado cartridge. I was extremely impressed. I have no experience with the other decks you mention 
Over a course of 9 years I have owned a Rega P5, P7, & P9.  All models were very good tables.  I recently upgraded my P9 to a VPI Aries 3, but had considered the RP10 also.  I chose the VPI due to the ability to 'fine tune' the table plus I was interested in an outboard motor to keep motor noise to a minimum.  I got  a great trade-in price for my P9 and have not looked back.  The VPI is a well engineered table.
Of the three tables mentioned, IMO, the Prime would be the choice.  But as an alternative, don't forget the VPI Classic.  Some prefer the Classic arm over the 3D.
