I've tried to use several $39 "import" detail guns over the years and every one of them has ended up in the trash can after it destroyed a paint job. (Maybe not the first on, but eventually it will) Spend the $ right up front and get the Binks detail gun. Take care of it and it will be the last gun you ever buy. I can't speak for anyone else, but in my case, you really do get what you pay for...
