12,000 BTU heat pump opinions

Well, summer is here; especially in the south. It seems our FROG A/C window unit ate it. And now after looking at the usual hardware stores and Sears, I just can’t seem to find a reliable window heat pump that is energy star approved.

I was wondering if anyone would be willing to give their opiions of brands in this category and possibly their experiences in an effort to find the “best” unit available.
