I was in a similar dilemma - I have a bit more land (about 14 acres) but I had been going back and forth between BX and B series and what do I "really" need. One thing that that helped me was to go to the dealer and test drive the models I was looking at. This was advice I took from a Messicks video - Neil said to put your butt in the seat and test it out. You may decide that a BX is perfect for your needs but then when you actually have a seat in it change your mind, or maybe a B2650 is what you decide on but then feel the tractor is just too big to navigate some spots.
For me when I drove a little BX around I just didn't like the feel and digging (my dealer had a dirt pile for me to play in ) with it just seemed to be a little too much work for it. When I tried the B2650 it was what closed the deal for me. A little more on the monthly payments but I felt good with what I was able to do with it. Those test drives sealed the deal and really helped finalize my decision.
