I'm looking at getting a skimmer, here is the information about my tank:

42 Gallon Cube Tank
10 Gallon sump, section is around 11in by 9in

Need recommendations on what to get, thanks for the help!

I love my orphek helix 5000!
I have a 46g BF tank with a 40b sump

You don't need a sump for it, but as one option I'd probably look at the Tunze 9004 DC model for system your size:

I'm afraid their smallest in-sump model, the 9410, would be too big.
