I was about to pull trigger on getting Fabfilter Pro Q3 upgrade (from Q2) when I got late XMas present.
Looks like I now have funds to upgrade to iZotope MPS 2, from MBP2, but don't have funds to get both before current sales end.
Maybe it's cuz I'm fighting a cold and its making me fuzzy headed but now I'm brainlocked about which way to go...
Arghh.
 
 
 

I get your pain ;)

It may depend on what else you have in your tool kit, but I would go with the MPS2 from Izotope.

iZotope just put out a $50 off coupon (HOLIDAY50 at checkout from the iZotope site) this morning for any purchase over $199 until 12/31, so that may sway your decision.

Does JRR Shop honor vendor coupons?

Then again, FabFilter is simply divine. And the upgrade price has never been so low.
