I started out pricing at Cobb Co. Tractor - they were the highest
Talked to Blue Ridge Tractor in N. GA and they had good pricing.
I ended up going with a dealer in Hendersonville, NC that also gave me a good price, and is also closer to where I am using the tractor. This decision ended up being the best for me due to several small service issues I had. Service tech made several trips to fix problems, and ended up having to take the tractor in - I wasn't even charged a trip charge and dealer is 10-15 mi away, plus another mile of 4X4 fire road to get to my machine. I like that kind of service!
Consider not just the price, but who you like for service, and how close they are - this is where you will really see the difference in VALUE over the years.
