The advantage here, is you can put it up high where it will take in the most heat. The mini split units like to be mounted up high as well. Of course being high is not as good for winter when you need heat, but the cooling aspect of these systems is where they really do well.

That was exactly my thought. For $1000 savings, I'm cutting a hole in the wall.
There are window unit heat pumps too, which will heat as well. Make sure they're actually a heat pump, many are just a normal AC with a built in electric resistance heater. Fine if that's what you want, but way more spendy to run than a heat pump.
