Rena came out with a new HOB not to long ago...http://www.rena.net/en_us/productCategory.asp?categoryname=FilterMedia
its pretty inovative...everything is independant of its self and theres a seperate bio filter that never has to be removed..theres also a hollow heater that can be attached to the intake end...still waiting for it to come out
Aqueon (new company) also came out with a new filter thats like the whisper but is also has some bio materals that stay in the tank... theres a biowall and a "wet/dry" feature
just wanted to give you guys a heads up :]
