I've heard complaints of severe orange peel but that may be due to the wrong reducers when using that type of unit. I used a friends to do a few things and was extremely happy with the results and I'm no pro by any means. I especially like the lack of overspray and fumes !! Not having to worry about moisture or contaminants in the lines is definately a bonus. The big hose attached to the gun is probably the only downside. It'd be really cool if they made small (touch-up) guns for those units.
