Looking for compressor for high volume of shooting let me hear your experiences.

Looking at something like the Bauer JR. Will be needing to fill 100 cu ft tank a few times per week, and also be able to fill local shooter tanks. Will probably also buy a 6k bottle to keep constantly filled to fill from. Anything cheaper than the Bauer that will work? I know the Bauer is an industry standard my friend had one for many years for his paintball field.
 
I love my Daystate and use it every week, but if I was going to be filling other people's tanks, I'd save more and buy the Bauer. Primarily based on the longer reported time between rebuilds. Perhaps the Airetex. It is a bit cheaper and seems to be reliable. Only downside is it weighs twice what my Daystate does. I don't know about the Bauer 's weight. The Daystate is easily (sort of) moveable. I doubt I could move the Airetex around by myself.
