I went to Kubota site and did a build and with all of the extras listed the msrp was $28846. Wow! Did your quote include any of the extras? They added just under 1K. to price. Maybe you can negotiate to include some or all on price and then it would be a very good deal. Or e-mail Barlows and click the build on their site and list options you want. They deliver to your area.
I would suggest you consider the mechanical thumb (big thumbs up on that) and possibly the FEL q/a if you think you might want a set of forks. You probably know the 3300 has no mid pto. That is main difference and the larger R4 tire size (and cruise control) between it and 3200 (and only the R4 tires are different as ags and turf are same size on either 3200 or the 3300). btw, how do you like the MF1529 you have?
