I used UGFs for the better part of 20 years. Just set up my 55 again on 1/1/9 and used it for 4 months and switched to a Marineland C-360 canister and it couldn't have been a better decision. I pulled 1 or the 2 filter plates out and made a glorious mess. I thought I'd do better on the second (2 weeks later, allowed time for bio community in canister to ramp up) but it was just as bad if not worse.
Now, my tank is easy to maintain and clean. I will never go back. And if you read enough threads, you will find one of mine where I defended / justified it for a while.
Also do yourself a favor and buy a Python. They rock. Big Al's Online has great prices. I've seen a knock-off at Wal-Mart and Petco which I'm sure it fine but Big Al's has a great price on the original.
