Id rather go with a Filstar XP-3 if you cant afford an Eheim. My lfs did not recommend Fluval. His reason was because of bi-pass were the eheims and Filstars are better. How does I guy tell though. Some people say the Fluval do not have any bi-pass where others do. Its like opening a can of worms. Anyhow, my Filstar works very good, very quite and easy to work with ie. cleaning, assembling, etc. but not the high price as eheim. Customer service is excellant not like Walmart (Ouch)! 8) Also see other topic Rena Filstar XP-3. Also the website: http://www.aquariumpharm.com/catalog/aquarium/rena/filstar/rexp3.htm
