i just bought a rs135 for my 90 gallon. the pump and skimmer is a lot bigger and better than the rs100, and its only 50 bucks more. it was easy to set up.. and started skimming right away. it is also built veeeeeeeeerrrry welll
I had an EV-150 on my 115 for over a year. It worked well enough. Hard to beat a Euroreef. All depends on how badly you want to save $150, because imo the EV could do it if you're not heavily stocked.
I've never owned a EuroReef, so this is one sided... But, my 250 gallon system is skimmed by a AquaC EV-150, and I have no desire to get a bigger or different skimmer...
(Granted, I use large refugia in place of heavy skimming)
I have been researching the same skimmer's for my 90g. The only negative that I have read is the Mag pumps are loud. I guess it would depend on where the tank will be.
I have looked at the ASMg2 also, it is $245 on Ebay.

The ASM G2 will be your best value for performance. It will use less power then the Mag on a AquaC. Euroreefs are excellent but overpriced. I would put money on a euroreef or ASM vs. the AquaC of equal size. Not saying the AquaC is not good, just my opinion.
