upgrade or replace rega planar 3

Hi all,
Just looking for some opinions here. I have a rega planar 3 with an rb600 arm and a denon 103 cartridge. I have been bitten by the upgrade bug. My question is is it worth doind the various upgrades to the planar 3 sich as a deep groove sub platter and acylic platter, or should I just scrap the 3 and upgrade the whole table? Any opinions either way. My budget for a new table/arm combo would be around $1,200.
I listen to mostly rock and jazz.
Thanks
