I just became the new owner of a RZ system, lightly used. Externally it appears to be perfect. Mechanically everything seems to be in working order. However, it has been sitting in it's original box for two years. I would like some recommendations as to a technician/shop, who can give it a thorough CLA. Prefer to keep the body in USA to avoid customs. Currently living in NY state, two hours north of NYC. Thanks for any suggestions.
