You need to concentrate more on the size and installation of your air conditioning unit, rather then a high end air conditioner. Since the huge aspect is the installation, if it is not installed appropriately, you will face more issues later.
One great reason to have a correctly sized air conditioning system is humidity control. When it runs, the evaporator coil temperature is below the dew point temperature. The result of this is that the moisture condensing on the evaporator reduces the moisture in the air. This would suggest a decrease in the humidity. This process cannot happen with a large air conditioning unit, as the run cycles on them are too short for this to happen. So keep that in mind when youre going shopping around.
Also, maintaining and repairing an over sized air conditioning unit can cost you a lot more. The compressor for example, gradually, will wear out and you will have to get it replaced. If your air conditioning unit turns on and off for 4 or 5 times in an hour, instead of the normal 2 or 3, it will wear out your compressor. There are many other aspects to watch out for when shopping around for an a/c unit, so be sure to do some research and not hesitate to ask questions.
Now, at least you understand its not all in the name. Be sure to pay the additional money and get the air conditioner installed appropriately, because that is the main thing.
