yeah about $60 is a good price (dixie arts price) and they have free shipping on items over $45. (thats the price on the kit)
When you order it get you an extra needle too.. (about $5 each) nice to have at 11pm when you are trying to put that last little camo on and yo drop your airbrush on its' tip!
I have a 155 and if you don't already have any some needle lube is good to use with the 155 (actually any AB) keeps the needle cleaner and makes the pull of the trigger smoother. I swear by the stuff! Another $5 at dixie art, and the bottle lasts FOREVER
