As I noted above, I bought from Carver and I am very pleased. I will say that there were a couple of mix ups (like they sent the wrong top link) but they took care of the issues and shipped me new items right away. They were very professional in taking care of my needs. As you can see I live in NY and they are in NC. I found them searching for used Kubota's and came across their site. I requested a quote from them and several others dealers including local ones, but they were the best price including the delivery here to NY.
The only potential concern I have is if I need Warranty work, will I be able to get it done relatively locally (ie. within 50 or so miles I have 3 dealers). Time will only tell if a need for warranty happens. I currently have 50 hours on the unit (in fact was doing service tonight, and found out half way through the local dealer gave me wrong oil filter so it sits out there waiting for me to go back tomorrow to get correct one).
Good luck, and make sure you consider the warranty repair in your equation. I did and decided it was worth the gamble. Hopefully I am right. But you definately have to figure that in the equation or you will not be satisfied long term.
