The Exclusive P10 is reportedly very close sonically to the P3 and should give you more leeway financially.
I own the P3 and have owned two P10's. the P10 is a very nice table, however the P3 is in another universe as far as as sound quality goes.
Outside of the parts of the tonearm - its very cool being able to swap arm wands between both tables, everything else on the P3 is built exclusively for the P3 and is the best table Pioneer knew how to make and it sounds amazing.
