Don't need to spend anywhere near that much. Like I said: doesn't need to be a super expensive high-end brush. Just needs to clear the floor for reliability. My HP-CS was under $100, because I got a refurbished classroom brush instead of a new one. Badger brushes go for less even new: they're not as easy to clean as Iwatas, but they spray well. A used brush from a reputable seller is better than a new brush from an iffy one. And like I say: If you're even thinking you might upgrade later if it works out, that's enough to tip the scales and make it cheaper to just buy the "upgrade" first. Only reason not to is if you're anticipating an upgrade in your financial status. Otherwise that same money is gonna be coming out of the same budget situation regardless of when.
