I've got a top that I'm developing that I think you might be interested in. My target price is $275.00 Plus shipping. If your interested contact me at dannywilliams_52@hotmail.com and I'll send you some pictures.

P.S. I'll have a Web site up soon, displaying the top as well as a hydraulic top link kit for the BX and a set of upgrade anti scalp wheels (for those of us that run with the wheels contacting the ground). The wheels will have stainless steel roller bearings and a grease zerk.
Kubota makes a canopy specifically for the 2200. I purchased mine from the local Kubota dealer for around $385. I thought it was a little pricy but was actually cheaper than a curtis cab canopy from Northern Hydraulics. The dealer said the u-bolts on the Curtis canopy would not fit the roll bar on the BX.
