its not overkill (if anything the opposite being a HOB). I'd grab it at half price of retail. $150 is what it should cost new considering the pump is a maxijet with pinwheel. anyhow its small, quiet, effective and the pump isn't in the tank which is what most people want out of a hang on back. at $150 you can always sell it at no loss since it has Deltec stamped on it.
