In order of preference:
EV SX300 (200)most expensive of the three
Mackie i300
Peavey PR12 (15)least expensive.

All three would benefit from a powered sub like the EV Sba120, especially if you're running your keys and sounds thru them.

I think I said the first time you mentioned those Cerwin-Vegas that you should dump them. I'm not a fan of JBL's, tho they are good speakers. I think the EV's are livelier, while the JBL's are rawer and deader. The Mackies are a nice compromise and the Peavey's are a great bargain for the sound.
