I just can not understand the crazy prices on all the old dozers. They have already paid many times for themselves, over the original cost from when brand new. They all have high time and likely fatigued parts, I have seen them with cracked out main frames. Then there are the jippo fixes on engine blocks, and things like welded transmission planetary carriers and the list goes on. Leaking at the rear plate caused by all the inner bevel gear case to rear plate welds cracked, I've seen it all. Its all just a lot of money for a pile of potential scrap IMO. The only old D8K's that maybe worth it are some of the ex military ones that show up on occasion.
