Repair & DCC installers?


So looking to have some possible repair work and DCC / Sound installed on/in a 2 rail Sunset / 3rd Rail articulated. Maybe a number change on a tender. Suggestions of who to seek?  Please be honest and fair. If you can not recommend, just don't.   Let's not get negative or nasty. I looking for the great.  Thanks, Bruce in Mount Airy, MD
