There is just a whole lot of stuff out there in the 25 - 35 hp range. I spent a lot of time narrowing it down. It sounds like you need to check out what the dealer parts/service guys are like, sit on and drive most everything you're looking at, compare weights, lifting abilities, maintainence needs and costs, ease of doing things like checking/changing the oil and filters, just everything you can think of. Pay special attention to how it fits your body shape -- is there room for your feet and legs to move the controls easily? Can you reach everything without getting into an uncomfortable twist, stretch, etc. It's going to be a matter of which tractor has the best combination of things most important to you. The way the rear stabilizers work is important to some folks, the way you adjust the level on the 3 point is different from one machine to another, whether it includes the drawbar and toplink, is there a little clip to hold the top link out of the way, are the lower link ends telescoping, is the seat well sprung, where are the lights located -- will you likely knock one off doing some particular job? -- how do the headlights work if you ever plan to use it at night, etc. etc. etc.
Look carefully at the loader and bucket construction if you plan to use it a lot. That, the seat, and the lower link features finally made up my mind between two red brands. Some buckets are light duty, some are medium, others are heavy. What do you need?
As has been said you have a couple of basic no-nonsense traditional type machines in your list along with a couple of more feature laden new ones. You and only you will have to decide what you want and/or need. Those are all very good machines and any one of them will serve you well for a long time. You just have to figure out which one you like best and then don't look back.
You have the easy part completed -- finding out what's out there in your price range. Now the fun starts. After you narrow it down to one tractor or dealer, you get to think about tires -- R4, R1, or turfs, loader options, QA or not for the bucket, and so on. It took me about a year to finally decide and I'm hoping the one I got (Case DX-29, QA loader bucket, Ag tires, rear hydraulic valves, HST) won't be too big for one particular use I have for it. Enjoy the shopping!
