Best window AC unit?

[VetteOwner]

I just need a small one as my apartment is only cooled by a single window unit, cold air does not get to the back bedroom but would like the most efficent one, ill prolyl run it more than the other one as i spend most of my time in here.

Looking at around $100

All new units should be labeled with a SEER or EER rating so you should be able to easily compare efficiencies between several brands/models.

ive seen the energy star efficiency and estimated yearly cost but im looking at quality too, dont want an efficient one that craps out in a year...

Check craigslist, i see them all the time. People put in AC and no longer need their room coolers. Thats ok if you want used.

A couple of strategically placed fans, set on low would make a big difference.
