As to the RFN end - if he's an old guy who loves scopes - see about takeing it in to him and picking his brain about maintenence and scopes while he does it or guides you through doing it...

If he's a $$$ grabber, shop arround - you CAN find a guy that loves optics and would love to share a few hours talking about how to clean um and all sorts of other related stuff! - BE A SPONGE! - find the right guy, even if he's not from the "right" company...
