I'm a big fan of overfiltration. Rena XP3 (or your equivalent of choice), wet/dry, maybe another smaller canister or HOB... At least a pair of good canisters. A lot of it depends on fish choice, if you intend to plant it, etc.
you could try one or two of the new FLUVAL FX5. they're supposed to be pretty good.
I personally would look into an Eheim wet/dry system or perhaps 3 Aqua Clear 500's it's really up to your preference on fish and bioload.
