I got lucky and 3 Dueces came up for auction in Helena, Mt. They were DNRC rigs that the DNRC had only had for a couple years. I got the best one of the bunch, was able to test drive it before bidding on it. She purrs like a kitten, only things was we had to jump her because the batteries are shot. Any suggestions on best place to pick up a couple & what's the best size? Also thanks for the link on the manuals, now I have several hundred pages to read, but what a great resource!
