Inexpensive paint, gun worth considering?

I had good luck spraying 2k paint in engine compartments with Harbor Freight detail guns, the one that comes in the two gun kit. The cheaper Harbor Freight guns have worked great for me but after some use they tend to crud up won't come completely clean throw out get another one. I have a nice Devilblis I sprayed clear with once nice gun pricey.

For spraying epoxy primers I like the Harbor Freight guns use them to do one car throw away get a new one for the next project car. Disposable cups make for some quick easy clean up too.....
