Sounds like some good choices there. You'll be happy with any of those tortoises.
I definitely know what you mean about having to carry a 100 pound tortoise up and down the stairs. That's why I've stuck with my red-foot and my russians. Someday I would love to get some other species, but probably some of the rare small species like egyptians and pancake tortoises.
I keep going back and forth on getting a sulcata or a leopard. I would love to raise a large species of tortoise, but in this climate it is not meant to be. I only have a few months per year that are nice enough to keep tortoises outdoors, and even then it is just not safe to leave them outside overnight or when no one will be home. There are so many predators around my neighborhood, man being the most feared. I couldn't imagine having a tortoise over 40 pounds that I would have to take outside for a few hours, then take back inside, not to mention finding adequate indoor housing for such a large tortoise. Granted, leopard tortoises take a long time to grow, but as the tortoise got bigger and bigger I would be getting older and weaker.
Live within your means and you (and your captives) will be happier for it.
