I too am going with the b7500 in about 2 weeks. I was quoted b7500 with FEL and R4's for $13, 150. Not sure on MMM. This was without tax of course. Let me know how it goes.
I don't know what part of the country you're located, but here in E. TN we were able to purchase a B7500(DT) w/ R1's, Woods 1006 FEL, 60" WAC RMM, and a Pyramid 4' box scraper for 11,700 delivered.
ridgeRunner: seems to me u got a great price, last year the best price i could get on a 7500 hst, fel& r4's was $12,500. did not buy it got a used b2400, but my point being that so much depends on the area of the country u are in. can't understand whay there is such a big diff. in the prices./w3tcompact/icons/eyes.gif
