Hi, for those who reading through this this discussion. If you are looking to do anything to your NPR...upgrade, service, modification, need accessories, the guy you want to is George Zorzoli at Optical Electro House in Burbank. The next person you want to talk to is Les Bosher in Wales. I've dealt with all others and these are the best places because they deal specifically with Eclair, George especially, and they know what they are doing in detail. No hack jobs. Les did an incredibly gorgeous S16 conversion on my npr. Call George if you are in the states or Les if you're in Britain.
From time to time motors come up on ebay. The Alcan, although very ergonomic, is not considered the best motor. George could give you a better idea of what you can get and I'm sure he has somthing. SMS Prod. in Chicago had a used Perfectone motor for sale that I used as a backup motor on a shoot. They wanted $500 for it. The TCS is great for the studio and doing precise frame rate control but it is very heavy so hand holding can be a bit arduous and painful.
