Is there any advantage to the Iwata HP C Hiline compared to the HP C? Is it worth the cost difference? Thanks.

Greg:

The big difference between the Iwata HP-C and the HP-C HiLine is, I believe, the inclusion of a air-flow control valve on the HiLine series. This valve allows you to set air-pressure at some constant right on the brush- parallel to the pre-set handles which allow one to set a limit on the amount of paint you spray. I'd say that the air-valve would be worth some extra bucks - I have HP-C airbrushes with pre-set handles, which are great- and wish I had an on-the-brush air-set device to compliment those handles! Great things for those aging fingers which are no longer as steady as once upon a time!
