Does anyone have any tips for using the on board camera during the show? I dont want to make controling a camera take too much attention away from running the show. Do you have any tips for touring with 3 DL2's? What would you recommend keeping as spare parts? The tour will be going to some remote places that wouldn't have a computer store. Also they will be used about 50% of the time on the same generator with other movers, leds, 10 colorcommands and audio. Would you recomend a power conditioner/regulator or a UPS?
