Here is my suggestion.
Go to the websites of different Kubota dealers that you are willing to buy from and get quotes on exactly what you want, including the equipment. If the dealer that you would prefer to use isn't the lowest, I would pay them a visit with a printout of the lowest quote in my pocket. I would explain to them that you really want to buy from them but you have lower quote(s) from other dealers. I would keep that quote in my pocket unless I absolutely had to pull it out. If they are willing to deal and you show them that quote, they most likely are gonna match it or beat it by just a few bucks.

But.. as some have already mentioned, I would definitely consider the service after sell aspect when making the final decision.
