<hijack> To which I would say this: the local stage lighting & install company will charge the same amount for repair if you bought the gear from them or not. They have no warranty except the manufacturer's warranty, and they maintain this philosophy. The only other local place is the place that completely ripped us off on the lightronics retrofit to the hardpatch system when (if their electricians were at all competent) they knew that the system that they were installing was out of code. Basically, the only option around here is to buy through an out of state retailer, because all of the local companies rip you off and then charge you the same amount for labor as they would anyone else who got their gear from average joe internet retailer.</hijack>
But this is only my situation. In the DC/Bethesda/Montgomery Co. you should easily be able to find a company that can provide a low bid on the NSI gear and be able to provide maintenance when necessary.
