I'm no paint/body expert. The last few months have been my first painting experiences. I am using the cheaper Eastwood gun you are looking at. I've been happy with it and also have a small 2.5hp compressor.
The gun DOES get shipped to you in a pretty dirty state. They paint it black and there is a bunch of left over black mess in the internals of the gun. It's not to difficult to clean out, but you must make sure you do.
Here are some pics of things I've painted recently with the Eastwood LT gun...
You can see what the pattern looks like.... I don't have much experience, but I'd think it could be on the smaller size than other guns... This is using a 1.5 tip with an epoxy primer.
The paint booth had a pretty good compressor system, so it wasn't too big a deal. At home, doing a door here or parts there is no big deal. With a 2.5hp, 30gal tank, it would kick on once per coat on a door.
