Our 10 year old garage door opener's logic board went out so I went and bought an entire new opener at Lowe's instead of fixing it; the best solution as it was just $35 more to do it this way. I am looking for someone in Hernando County (hopefully) who can professionally install my new one...Lift master to Chamberlain, same hp. Most important to me, quality of initial install, warranty, follow-up on initial visit if any problems and price. Anyone?
