I purchased one of the other Aaton packages from Alan Gordon a month ago. Shot a couple rolls and it works great, checked out the workprints on my Moviolas.
There are ground glasses at Oppenheimer Cameras. I bought a clear glass with no markings from them - He's got a bunch of standard 35mm ground glass as well including an anamorphic one. I also got rods 4" and 2" from them. They still have 6" rods. If you need 4" and 2" Aaton in France have them for around 200 usd.
My main concern is where will we get our cameras serviced if something happens? Ablecine is not doing it anymore, I think we would have to send to Aaton in France, unless there is an independent tech with Aaton 35 experience here in the US. If anyone knows one let us know.
Congratulations on your camera !
