FWIW, we got a Coralife SS220 when we set up our tank - we're still new to this (tank set up in May and our first tank ever), and have had one SS220 fail on us, and are about to replace it as we upgrade our system to a better sump with a fuge.
I'll say it carefully, especially because I'm no expert, but I was very unhappy with the Coralife SS220, both in terms of quality, need to constantly adjust, issues with air intake, and difficulty in finally getting to the manufacturer.
Our lfs did a great job of supporting us by replacing out of stock and handling the return on our first failure, so that was appreciated.
But the quality just isn't there in my opinion, nor is the design. I'd look to better quality units - this seems to be the main area where you don;t want to save money, you want the best, and easiest to maintain since it's the heart of your system's health.
