Rega P25 with mods or new table?

I may have the opportunity to borrow a used P25 in excellent
condition from a trusted family member who takes extremely
good care of his equipment.   

I was considering purchasing a new Rega Planar 3 2016 version (when it
is released in the near future), or a new P6.  

Before purchasing a new table, would it make sense to upgrade the 
P25 instead?  

A properly set up spec P25 is basically on even or superior sonic terms with all Rega decks with the exception of the P7-P9-RP-8-RP10. Save your money with mods and get a used P9 or RP10 then make some minor upgrades-mat-feet-record weight ect.
