good choice. i started with a coralife 125 a few years back myself. hated that thing. couldn't get it to run consistently, it was always overflowing, etc...
i also switched to Reef Octopus, and have been very happy with them.
they have very good support too. the second RO skimmer i bought had an issue with the cup not fitting correctly. i thought it was the silicon o-ring around the back of the cup, so they overnighted me a new one, free of charge. that turned out not to be the issue, so they overnighted me a whole new skimmer cup, free of charge. fit perfect.
both the RO skimmers i have are still running, flawlessly with only normal pump cleaning for about 3 years now.
