The adjustable on my Camspray 1500a just bit it but I'm having a hard time finding anything to replace that might be an upgrade. It's all "turbo rotary" or whatever.
I like the adjustable- it's a fan spray and I use in a tighter pattern for reclaim, wide fan for resolving stencils. An upgrade would be a quick change tip- one very even, wide fan for resolving, one tighter, more agressive for reclaim.
It doesn't look like you can find the industrial tips at lowes/home depot.
