I am getting one for a 30 gallon seahorse tank. It looks pretty cool as far as features go, but like you, I couldn't find anyone else that had used it, so I had to go out on a limb and get one. I ordered the TetraTec 300 with the optional heater, and with the $10 rebate from TetraTec, it is going to run me $40 delivered to my door. Not too shabby.
