thanks for the help guys, I have done the roller texture thing before, and it looks ok although its hard to get a uniform look in large areas, but im looking for a smooth finish so im not looking for the old fashioned pointy stuff look, im looking to do the same orange peel texture they do on walls. it looks flat but that's what finish they do one ceilings now.
I have never seen a ceiling done that doesnt have at least an orange peel finish. there are just way too many minor imperfections that would stick out from a mile away if it didn't have some sort of texture to hide it. you just cant get that much flat area to have a perfect finish and not need some form of texture to cover and hide all those minor finish imperfections.
someone sent me a link to this:

im going to buy this to do it since I already have a compressor for it.
since I wont have to be renting the machine to texture with, I can do as many one room at a time areas as I need to.
