Which amp?!?! Rev 8's

Hey guys, I have been a lurker for quite a while and have never needed to post anything that I couldn't find out by just searching... Well I have been searching, reading, searching for over a week now, and I figured I'd finally just ask for some help.

I just got a new pair of Rev 8's thanks to the great fella's at Wet Sounds (Tim and Robert). I had a pair of Pro80's that were powered by a Cadence TXA-3004 bridged for 300x2 @4ohms, but after about 4years it has died on me...

I need something to power the Rev's but I really don't want to spend over $200 on another amp.

I currently have the 5 channel Fusion marine amp which are powering 4 polk in boats and an Exile 12. I wouldn't mind getting another Fusion, Cadence, or really anything that is decently cheap and can still throw 300+ RMS at these guys.

I have looked at the Cadence D100.4 or fxa-4100.
I also like the Fusion CA-DA41400 which says it can do 440x2 @4ohms.
Last but not least, the Exile SM400.4 400x2 @4ohms. (leaning towards this one atm)

I know this topic has been brought up several times, but I would really appreciate some opinions before I pull the trigger.
