Saw one in person yesterday. Beastly machine but will need some counterweights to lift anything of any real size. It had a hard time picking up a 54" Dutchman tree spade without the tree, without hunching the back end up.
Based off what i paid for my 297c, i wouldn't be surprised if the 299D was in the 85,000- 90,000 range. Heck could be more they are proud of that yellow paint.
