Braz, how big is your compressor?
A common misconception is that the HVLP guns don't need much air, when they usually take more CFM's to get the paint through them than a conventional gun.
I use a Devilbiss Finishline3 HVLP for basecoats and it's a good low priced gun that in my opinion does a great job. Very little overspray.
Another gun you might consider is a Sharpe Platinum. It's not an HVLP gun but it doesn't use much air and is (from what I have read) pretty easy to control and won't give you too much overspray.
