Skimmer for a 20gal

[SGT Henry]

Whats a good skimmer for a 20gal long tank...just 12 inches deep and its gotta be small so it wont look bulky cause I dont have a sump so it will go hanging on the back of the tank...

Thanks, any help with a good model is welcome

Not more than $100 preferably

eBay and other places have the generic version of the cpr bakpak2. Works just like the real thing but only a fraction of the price. I paid $70 for mine.
