I received delivery of my TC33D with supersteer, 7308 FEL, 72"mm and 6' rear blade this week and just went through what you are going through because I did not have preference for color.
I first determined what my primary use would be which for me is mowing 5 acres weekly then secondary uses i.e., driveway maintenace, landscaping, gardening, etc. that requires light loader work. Also, I wanted to make sure the tractor size would not be too heavy to damage my lawn but large enough to do most other work I anticipated doing. Based upon my set of priorities, I then research each tractor for fit and then visited dealers for test operation and evaluated the quality of the dealer. You will find that most on this forum put much emphasis on dealer because if you ever have a problem you want someone local that will back the tractor. There were many other factors but those were the key ones.
Based upon the above priorities, NH was the best fit for me because the supersteer is great for mowing and I liked the ergonomics of levers, seat and curved hood for ease of sight for loader work. I compared the NH TC33D, JD 4310, Kubota
L3130 and Kioti DK35 which was the order of my choice as well. I was also very interested in the Massey 1440H (which is the only mfg. with turbo on this size of tractor) but no local dealer. If my priorities were more focused on loader work, I probably would have chose the JD due to more lift capacity of JD loaders but the Kubota would have been very close second since dealer is closer.
As far as price, the dealers in my area are all very competitive and easy to work with. I had dealers give me there best price with comparable equipment and found Kubota to be cheapest, NH second and JD third. The Kioti dealer was way over priced when comparing the tractor to the other three. There was only 5% difference between highest and lowest bid. I don't brow beat for best price but did tell the salesperson to give me their best price because I was getting quotes from the other dealers. That worked well in my area. I also got quotes from dealers on this forum to see if my dealers were competitive and they were.
This is rather winded but will give you how I approached this important investment decision.
