I wouldn't worry about the lack of a bio-wheel. The principle of the biowheel is sound but they really aren't big enough to make any difference. You'd need an enormous one which isn't terribly practical.
You'll love a canister. I switched from an AquaClear 70 HOB
to a Rena Filstar XP3 on my 55 and it is great. Easy to clean, no waterfall noise and no hulking filter on the back of the tank.
I am not familiar with the Marineland canisters, hopefully someone who has one can chime in here. I have two Filstars (an XP2 and an XP3). I have heard many good things about the Eheim and Fluval canisters as well.
