With the exception of the Max, those are all way to small. What is your history with tractors, how much of what you want to do have you done with other tractors? I'm sure most of what you want to do could be done with a SCUT, but it's not what it's made for.
I have 3 acres, do most of the same stuff you're talking about and have a Kioti DK45. I started with a JD 955 (33hp, 1700#), traded for a Kioti CK30 (30hp, 3200lbs) and then finally the DK45, all in 2 years. It's cheaper and easier to get the right machine the first time.
If you only want a SCUT in the future, rent a Kubota B26 or L39 and get it done, then maintain it with the SCUT, but I think you're going to find that you'll really want a bigger tractor. I've never had a SCUT, but my DK45 doesn't seem any less maneuverable than either of my previous smaller tractors. I'd look at a Kioti CK30 or DK40, a 30-40hp LS or possibly a Kubota L3240 or L3940. All great tractors, a little more $$ than the CS, but not that much more than the JD 1026R that you're looking at (well, the Kubota's might be).
Oh ya, until you sit on the seat, they won't quote you much more than MSRP.
