electric trailor dolly

For those of you who have any electric trailor dolly - where did you get it from and how do you like it. I tore my rotar cuff - shoulder and I guess my days of trying to get the TM in the gararge with the manual dolly are gone for awhile. I am really thinking of an electric trailor dolly but due to the cost wanted to find out what the experts are using. Thankd for your advise.
