Has anyone ever used the Iwata-Meda airbrush repair service? For $20, I wonder if the service is cost-effective (replacement parts are extra and believe me, they cost a lot!).

I replaced my nozzles and needles, but somehow my Iwata HP-C never behaved like it did when brand new. (And now they have the HP-C PLUS and HP-C Hi-Line). I'm kind of wondering if it's better to buy an upgraded Iwata than trying to revive an "old dog."

Comments welcome. Thanks.
