Guarentee a 3320 HST R4s, with a 300CX with 73" HD bucket/grapple/toothbar and good rear ballast and loaded tires, a 72" 7-iron MMM and/or MX5or6, BB2072, and 3rd valve with loader plumbing for grapple, and the boom mounted 72" snow plow will do everything on that list! Add in a tiller and or other items if you need other handman tasks done. Do you need the turbo for elevation reasons at all?? Your tasks are not requiring more PTO HP. You best bang for the buck for those tasks is still the 3320in my mind - put your money in the best implements you can afford.
If you want lots better you will be moving to the 4X20 line to get a wider stance and larger snow plowing capability, a 400CX self leveling loader, bigger mower capacity, and a host of other capacity increases.
I would base this decision on my elevation.
