Josh, I think that the Remora pro would be a very good cost effective choice for you.
While you can't over skim, you can skim reasonably well with the Remora and Remora pro.
I use the Remora (Not the pro) on my 90 with very good results.
I'm sure that someone is going to tell me it's not large enough for my tank, but keep in mind that there many other people that keep just about everything without skimming at all.
So my opinion would be that any skimming is good skimming and the Remora skimmers do give you realy good bang for the buck.
Search around the net and see what others have to say about these compared to other HOB skimmers.
