They are Cheiftec Dragons. The left one I bought around 2001 or so and the other one I bought back in 06 or so. I actually bough six of the one on the right around 06'. I still have 5 in the closet still in the boxes. 2 more blue ones and 3 Yellow ones. I also have a green one I bought when I bought the first blue one. It houses the 940be x4 system.
