Anyone use one of the Harbor Freight HVLP guns for shooting latex paint? If so, did it work well?

I've shot latex successfully with a higher priced HVLP gun and a large tip, but I don't want to keep using latex in that gun. I was hoping that I could find a cheap HVLP gun to shoot latex.

Here's a selection of the Harbor Freight HVLP guns. Any comments?

I don't want to spend the money on an airless unit unless you can suggest a low cost one that works well.
