I have the kick back and have moved several pins with it as well as using it for heavy things at work. It is very nice when lifting something really heavy to just be able to relax for a second on the kick back wheels without needing to rock it back forward and then back up again. None of us are getting younger, so all the assistance I can get is great. I had to move a pin through a backyard and even having the extra wheels for a "just in case" scenario was nice too.

Not sure where you live, but if I remember, I got mine from Northern Tool and saved on the ship to store option.

I personally wouldn't get another appliance dolly without the kick back wheels.
