I was going to purchase a belt drive last time my wife backed into the garage door, but never got around to it.. I fixed the the bent door to get me thru the winter, fixed the bent track, same reason. This past summer, I finally got around to installing a new garage door, and picked up a cheap door opener and installed it myself. I have the big single two car garage door...had installed $800...my opener was $98. I only cursed a few times, installation was free...it opens...it closes, I'm happy. I don't let my wife park in the garage anymore, it has two XF's in it....lol...problem solved..
