at work there is a small conference room with a unSit. Not small - it is shorter, but also wider. I like it and often reserve that room for an hour to get some steps in. However I've never tried any others and so I can't say if I'd be unhappy with the others. I did find a free craiglist treadmill a few years ago, but the setup I had with it meant I was rarely using it.

I don't think I could stand/walk at a desk all day, but I still want one because I could easily do several 1 hour blocks during a day and it would be better. However some ability to get a chair seems important if it is at your only desk.
