moodster,
I can't speak to the Remora unit, but I've been using a PM HOT 1 w/4" collector and nothing but good things to say about it. I don't disagree w/cjdevito, but maybe I just don't find cleaning it that problematic. Takes me around 10-15 mins. to break it down, clean it, and hook it back up. Skims beautifully, and adjusts easily. I operate mine in a sump, so the high profile cjdevito mentions isn't an issue in that application. I can see where it would be as a hang-on. HTH.
By the way, I replaced the Rio 800 that comes with it w/a MaxiJet 1200 w/venturi kit. Works just fine.
