I run a 2227 on a 55 and have no complaints about it... 140 is pretty good for it, tx trop has it for 189.99 (if I remember right) dont know about anyone else's price. If you do get it just make sure your air line is secured to the tank mine fell off and when the power went out it drained half of my tank out that was my mistake though. I use the eheim subtrat with it along with bio chem stars and kent nitrate sponge...all the parameters are perfect with it and when the "dry" part of the canister purges it shoots the water out alot guicker...my poor man's surge device.
