I found this 7800 btu model: http://www.sears.com/shc/s/p_10153_1...ationsAnc hor

And this 6000 btu model ($50 more):

I'm confused, based on one review on the 6000 btu unit, it sounds like
this unit actually completely shuts off when the temperature is
reached, vs the 7800 btu unit, where only the compressor shuts off..

Do they both do the same thing, or is the more expensive one capable
of shutting off completely.. the specs dont really say..

Anyone have any thoughts?

Thanks
