Query: An expensive alternative to spray cans

I bought this to spray colored stain but tried it out with oil based enamel paint first. Had to thin the enamel (rustoleum) 30-40% before it would spray properly. Yes, this works with thin materials close to the viscosity of water. Good finish, minimal overspray, easy application. Next I tried a latex stain. Even after it was thinned 50-60% it would not spray well. Totally useless for this material. Water clean up required a lot of scrubbing because the paint that gets in the air passages ends up being blow dried. I'm glad I have less than $55 into mine because its not worth the retail price. Buy spray cans instead, no clean up and less expensive.
