The Hyper 212+ is a fantastic value at $30 and whole-heartedly gets my recommendation. It's economical on space, too, and not a huge rectangular prism
Set it up in a push-pull configuration for best results.
Temps are hard to forecast, but I would certainly think that that 212+ will outperform the GeminII S by a good bit
