To jump on the Band wagon the AndyMark Trannys were awesome. We built 2 drive chassis this year in the first 2 weeks and at least gave our drivers some practice for the first time. Actually in competition we decided to take the shifters off due to weight and also the drivers said they rarely needed it anyways for this year's game. The kit transmissions were very reliable for our arm comtrols.
By the way you should check out our shimano brake calipers on steroids this year for arm stability control. It worked like a masterpiece.
Some day I'll try out the dewalt solution. Maybe next year
