Sata dealers?

[dcs13]

I want a 1.4 nozzle set for the Sata Jet 4000B I bought last month. My local dealer wants almost $400. There is a guy on ebay that "appears" to have the nozzle set for $215 . Looks like he sells a lot of guns and parts. Is there any concern this is not a real Sata kit ? Sorry, total newb here, just trying to make smart purchases.

Fair price, as SPI buys at a jobber from a WD. If he has a good rating, go for it.

Looks like he sells a lot of Satas and parts, and has 100% good feedback.

Thanks guys. This is my first "real" gun. It seems like Sata is pretty tight with stuff because no one sells them "online". His feedback is perfect. I think the 1.4 is a better nozzle to shoot a whole car.
