TractorHouse.com has a nice feature where you can see old auction results. If you do that for the Bobcat CT235 you see one sold for $13,000 with only 246 hours and a LandPride seeder. There was also a unit that sold for $10,000 that had 546 hours and rear remotes. That's not much to base a market value on, but based on available info I'd value the CT235 on CL at around $10K. Your local market will vary, and the condition of the tractor itself is the best indicator.
I wouldn't consider the Branson 2400H to be comparable. Bare tractor weight is 2/3 that of the Bobcat, the loader capacity is 2/3 that of the Bobcat, and the 3pt lift capacity is about 3/4 that of the CT235.
