Kubota site list price for MX5100 with 9' hoe is around 42000. That is with two rear remotes, QA on loader, R1 tires and a mechanical thumb for the hoe.
I don't know what options are included with that price you gave but it is not a bad deal, just not a great deal. Maybe the NY area is a little higher. I would suggest you go on the Kubota site and build the tractor with all the options you want then figure 10-15% off of that price for a real world estimate.
