Ogg was fairly easy to deal with, but that is because I had decided on what I wanted. The sales guy I worked with was Tony Bueso almost entirely via email. I actually had to wait for two months for it to arrive; it was on order, but they only had the lower HP GC models. Once it arrived, I checked it out, signed for the financing and they delivered it the following work week. I didn't have a means to tow it myself, but they only charged $75 for delivery and since they delivered it from MD, I paid no sales tax to MD.
Since then I have purchased fluids/filters from them, a mid-mount belly mower and a replacement lower link arm that I had sheared off. I have a backhoe model and it has been worth it's weight in labor savings and versatility.
I do my own maintenance so I don't know how they are for service, but nothing beats being able to do your own work.
It provides ballast without giving up it's function and the 3 point hitch parts collapse and sit behind the backhoe when mounted so that you don't have to disassemble the whole thing. My understanding is on a Kubota you do have to do that.
Are you considering a loader or just a bare tractor? I'm not well-versed in the Kioti models.
