I have the upgraded 1050a. Pretty good so far, although I don't have too many fishes and corals yet. The 1050a is rated for 300+ gallons. I was originally going to pick up one of the deluxe skimmers, but thought that might be a bit of an overkill. My sump is 80-90 gallons and I have rocks in there for filtration, plus my main tank has lots of sand.
Algae wise I'm still getting some, but don't have to clean the tank much maybe wipe the glass once a week. I think as long as I slowly add livestock I won't have too much of an issue. I keep the 400w radiums on for about 6 hrs.
