Matterhackers bed probing mod.....anyone try it?

My Prusa I2 has two things going against it.......I have an MDF build plate and it gets moves around a lot. It goes between home and different job sites. And living in NJ the humidity varies a bit. So I was looking into a way to automate bed leveling and came upon a few different solutions with z probing. Matter hackers (link below) seems to be the most document and successful. Has anyone got it working on there raprap? Dosent have to be on a Prusa I2 (be amazing if it was). Just wondering if it is a cool one off mod done by matter hackers or if others have done it successfully. Trying to see if its worth going for on mine. Oh and if anyone has any other suggestions for my issues, feel free to chime in. Thanks .

Exactly MPower, change it to an aluminium one.
