I have had great success with MaxiJets. And they are pretty reasonably priced. I would steer clear of Rio pumps and powerheads. I used to work at an LFS and we had several people come in and complain about them. Ive never had this happen to me, but, I repeatedly hear: when and if they seize up on you, the motor doesnt just burn out like other pumps. Since they are oil cooled, sometimes Rio's will release all the oil into the water when they seize up. In turn, your entire tank will probably die. I do like the maxijets though. And as far as pumps, I like Magdrives.
