It's all about the money. Less is best. Used would be OK however I'm not much of am mechanic to overhaul and maintain older machines.
I've done a bit of reading here and see that many seem to prefer the Massey or the LS over some of the more common machines.
Diggin it, let's talk about/review your priorities. Are you really all about the money or does the importance of tasks and function come into play? Sometimes the 2 don't go hand in hand depending on what you need the tractor for so it is hard for recommendations to be made other than the typical "I have this tractor it's the best go buy it." I have a few extra questions for you to consider and how you answer those questions can help you with narrowing down your options:
1. Do you want to take the backhoe off every time you need to mow or remove the mower when you put the backhoe on?
2. Are you ok with a pin-on only bucket (u can pay more to make it quick-attach) or do you want a quick-attach style bucket such as SSQA or Deere that you can swap loader implements?
3. Do you want to take the mower off whenever you have to use the 3-point hitch (using the tiller) ,-many SCUT's use the 3 point to raise and lower the mower deck
4. Do you want a drive-over mower deck or are you ok with one you have to slide in from the side (heavy & pita) <- Is your uncle's first name Arnold?

5. Are you storing the tractor in a garage with a standard height garage door? Can you remember to fold the ROPS before you enter the garage? (not being mean or sarcastic here - check for threads on guys damaging their garage door because they forgot to lower the ROPS.)
6. Are you paying cash or do you intend on financing your purchase? <- this changes everything if you are financing because interest rates change the true price of the tractor
These are some quick questions I have come up with to help narrow down your choices. Any other TBN members if you can think of questions to add for the OP please do so. Diggin, we want to help give you advice but you gave us 7 tractors to pick from which makes it kinda hard. As far as used tractors go, I don't mind helping look around quick to see if there is a deal to be had to point out to you but that requires at least a basic area of where you are at. Once again, you are not required to give us your location but that is why guys ask you for that info - so they can try to help with dealer info, prices in the area, etc. That is up to your discretion.
