I bought a used 60" escalera. Wish I had a taller one. Eventually I will trade up. Have toe plate and big wheels. I use the big wheels for every surface but the actual stairs. I don't regret my decision one bit.
That being said, even though I can move a pin by myself now, I really don't like to. The heavier the pin, the more work it takes to keep it stable. This is one of the reasons I want the longer one. People with the longer ones don't seem to have as many issues with the pivoting as I seem to have.
