canister filtres?

You can sometimes pick up a good skimmer used by watching this board and others. Another skimmer that works well is an ASM - bit more $ but a great skimmer - you have to run them in a sump though.
As far as HOB skimmers go I agree (again) with Albert the Remora Pro is a great skimmer although I do dislike the mag pump hanging in the tank.
