Hi Andy,
I think the Octopus NW200 would work very well. They should be instock in a few weeks.
Octopus NW-200 Needlewheel Skimmer w/pump
We do have an RPS3000 on clearance as well. It's external, but you can run them in the sump if you have room. It's on sale for 299
RPS-3000 Needlewheel Recirculating Skimmer w/pump - NEW
Some other skimmers I would look at is the AquaC EV180 or the Precision Marine Bullet 2. These are both very well built skimmers, but they do need a more beefy pump, especially the Bullet.
