Saw some online prices under $300 US, but yeah it's pretty pricey when you consider the fluval 404 / 405 can be had under $100. Then again they are rating it for 400g ?!? Flow rate is listed as a bit over 600 gph when under a load. One site I saw it at shows it at 50 watts of power usage. Always thought that they needed something a bit stronger than the 404 / 405 (100g rating), but jumping up to 400 gallons I didn't expect.
