One thing about buying what you like is that you won't regret the purchase.
As for the distance to the dealers, you can do a couple things. When you buy (from whoever you buy from) make sure they toss in free pick & delivery during the warrenty period. If you are doing your own oil changes, etc, have them throw in the filters & fluids for the 50 and the 100 hour changes when you buy the tractor, that way you won't have to go back to the dealer for a little while. Remember that the NH and the CASE filters, fluids, and mechanical parts are identical so you can buy your tractor at one, and the maintainence supplies from the other.
