Eric, welcome to HEF. I'm sure some other members have more experience that I do. They'll be asking you, what's your budget, what's your purpose or need? The tracked skids (compact track loaders or CTL's) are useful and productive. Depending on what you are doing, the push better, are more stable, and are useful in softer ground conditions. But I get them stuck, too. Compared to tires, they are definitely more expensive to own, i.e. track replacement costs, rollers and bearing, and labor. Will you be working in the cold? You'll want a cab (extra cost).
I own a Bobcat 773 and am happy with it, so I'm familiar and favorable towards the Bobcat line. I'm not crazy about the T200, the T190 is nice for light work but for what I'm used to, I stall it--too much traction and not enough power. For tough jobs, I like the T250 or T300. If money is no object, look at the new M-series.
There are a lot of Cats around here. Same deal though. If you're buying used, you can get into some track/roller/bearing replacement costs.
To get an idea what used Bobcat stuff sells for (asking prices, anyway), look at this site as an example. I've known Rod Lano for a while, and they sell and trade a lot of Bobcat units from their 3 locations.

Before you buy, try to rent a variety of machines and run them for a minimum of a day each. That'll help you decide what you like.
