I previously asked for opinions on Garage Door Openers and just want to update: i purchased a Chamberlain Whisper Drive (belt) from Lowe's. I had one of their contractors install it. Seems to be working fine, it's nice and convenient and does all the things I need it to do. The motor is quiet although I think the garage roof needs a bit of insulation as the door makes a bit of noise.
Thanks to all who gave advice to me... no spam--remove last 3 letters in address to respond
