could you tell me more about this spray unit. i don't understand the statement that it doesn't need an air compressor. how does it get the air for the spraying. and also if i do decide toget the tcp global spray guns what is the air compressor that is recommended to go with it?
<Harbor Freight not only makes cheap guns (which is a good idea for the reason nigich22 gave), but they make a great all-purpose sprayer that doesn't need a compressor for $120.>
