You might take a look at the Ryobi paint sprayer. I don't have one but I have a number of Ryobi power tools. I like that its cordless and you don't need an air compressor. Plus the price is reasonable if you already have a battery and battery charger. You might be able to find a reconditioned one at the Direct Tools store in Branson but I would call before you drive down there.
