Hey Muck,
I shopped around a little bit and the best price I could find was at aquariumpros:

The main competetor as I saw it was the Iwaki md-20rlt because it was pressure rated and japanese made (supposedly better than the american made iwakis). (They make a blue line to match each of the iwaki sizes.)
The blueline cost $40 less, made 60gph more, and used less electricity. Some people claim they are even quieter than japanese-make iwaki's but I have never been able to compare them. My tank is in the living room and the only noise I can hear is the water trickling over the last baffle in my sump.
