Reply to Upgrading studio!

Hey guys,

I'm currently on the look out for some hardware to add to home project studio. At the moment i'm running an iMac 24" 3.06 GHz Duo Core, 4GB Ram for my main production rig, with pro tools 9 software, 003+ rack interface, UA 710 Twin Finity Pre and Genelec 8020A monitors, Shure SM7B/SM57, AT 2050, Sennheiser E902/E906 microphones.

As far as softsynths go i'm currently using NI Massive, Sylenth1, Omnisphere and occasionally NI Absynth.

I'm looking at investing in some hardware! Mainly hardware synths but maybe another Pre and a compressor. The synths i've been looking at are the Moog Little Phatty, DSI Tetra/mopho key, Clavia Nord Lead X2 Rack. As far as compressors/pres go i'm pretty in the dark i know the FMR products are really nice, and i was interested in a ISA one for a very long time, but i'd like some pro advice if thats cool?

So yeah guys, what should I buy? I'll be returning from Paris on the 26th June, and then i get paid the following week so i'll have about
