Recommendations for electric tow bars for Sr20/22

I’m looking to purchase an electric tow bar. I have a hangar entrance that is slightly sloped and I need a tow with some guts. Currently borrowing one that has 24 volts and does the job. This retails for $1600-1700 plus shipping. While I may purchase this model I’d like to hear what others are using and would recommend. Thanks, Daniel
