[Rockhounds] air abrasive units - sticker shock!!!?

[Tim Jokela Jr.]

Thanks a ton, Tim, I really appreciate the info. Very glad to know that I 
don't have to spend a fortune on the air drying system. I have a couple of 
dust collectors in my woodshop right now, just collecting dust, and can 
build a work station in an hour or two, so two grand for a SwamBlaster and 
compressor seems pretty doable.

Cheers,

T
