I bought and used one of the harbor freight $150 sprayers, all you need is to buy a 30" paint shield and go at it. The hard part is learning how to prime it and disassembling the gun to clean. I used it a bunch. the spraying part is really enjoyable to watch how fast it gets the job done, but the cleanup is not. one tip is that you want to use a 5 gallon bucket with them otherwise you lose like half a gallon of paint just filling the hoses.
