Looking to buy a new or near new dozer to rent out. Thoughts on machine?

I buy and sell light, to mid weight equipment as a hobby and have long considered getting into the rental game. I would like to focus primarily on renting dozers as that seems to be a niche seldom filled in my area. I have owned nearly 100 different dozers, mostly d3's d4's and JD 450s, so I am familiar with the basics of dozers. What I am NOT experienced in is the newer machines. I rarely mess with anything newer then a 2000 model. If I buy one to rent, I will be looking at either...
