I have a chance to buy a d2. the machine is straight runs good ,pony motor is good tracks and sprockets good, pony motor clutch slips some and there are a few shields missing on the track adjusters and the left side of the frane by the engine. I have a d8 2u that i restored and use around the farm, but now i have caught the cat fever and feel i need to restore another, a d2 interest me because my uncle broke up a lot of ground in ND with it when he was young. could some one give me an Idea what i sohould pay for a d2?

I see them listed on Craigslist for about $3000.
