Ok, I'm not Jim but I gotta jump in. I love my Gen-X (new name for the MAK4). After my lighting upgrade later this year, I'm considering taking off my LG4 off my 75g and replacing it with a Gen-X. Way better pump, no comparison really. My LG4 is the pressure-rated, non-fan-cooled model. First of all, the LG4 gets so unbeleivably hot that you can get an electrical kind of smell in the air if there isn't a fan blowing on it (I use a 4" electronics fan). You could fry an egg on that pump without the fan blowing on it. The Gen-X, in comparison, is easily the same noise level as the LG4, and the Gen-X DOES have a fan whereas the LG4 does not. Plus it runs cooler, quieter, and draw less electricity to run, to boot.

Forget it. I am a total beleiver in this pump. Basically for the money, there is no better unit out there.

The only thing about it, I think, is that there is no way to oil the bearings so far as I can see. How this can be, to have a maintenance-free pump, I don't know. Makes me wonder how long the thing can last ... but hey if I get five years out of it anyways, I couldn't ask for more than anyways.

Carpentersreef does have a point about submersibles though. Definitely a lot easier to setup and deal with..
