I have been painting my indoor trim with a brush for decades and would like to start using a paint sprayer. Have been painting the trim with oil base paint. I am proficient in painting so if someone could suggest a sprayer that is somewhat easy to use and would hold up for painting once or twice a year. My main concern is overspray, uniformity, cleaning of the unit and thickness of the applied paint.

I paint the walls with a roller by the way.

Any suggestions would be greatly appreciated.
