I'm fairly new here so this may have come up in the past.
The accessorie that I would pay good money for is a [glb]detailed R9 Maintenance Video on CD or DVD[/glb]. This would include a very detailed video of taking the R9 down, cleanig/lube, and the reassemble. Could include some neat range video to give it more action.
I haven't received my R9 yet, but one thing I've learned from this forum is the cleaning can be a challenge. Some people who have been surviving the cleaning may also learn new methods to help them - look at the chop "stop" stick.
Has Rohrbaugh thought of such an item - am certain it would sell well - especially if on of the brothers did it. I would buy it though no matter who put it together. Lets say I'm a visual learner.
