I've used the harbor freight guns a few different times and they work really well for suspension and priming IMO. I don't feel bad having to toss one if I get paint all over it or whatever. The only complaint I can say is the paint will come out of the vent and around the threads where the cap screws on. I wait until they're on sale for around $15 and buy a couple. I have a Sata I use for body stuff. I can't remember the model of it right now.
