I just got my 5x7 Speeder back from Richard Ritter. The rails had been bent making returning the front standard back into the box a great big hassle. The several local shops on the West coast that I contacted couldn't help. On recommendation I sent the ol' Speeder to Richard Ritter and it just returned to me with the front standard sliding quite smoothly and at a reasonable price---especially considering the alternative of either milling new parts or (gulp) replacing it with a 5x7 Linhoff. If you have a camera problem that seems like an otherwise lost cause, He just might be able to help you out.
