I live in a condo building with 14 units and garage underneath. The garage door is very loud and so we're looking to upgrade to the Liftmaster Hercules model (HCT501130). We were quoted around $1,500 for the garage door openner and installation. Two questions:

1) Does anybody know anything about this model? Is it as quiet as I hear, and will it reduce the loudness of the garage significantly for the owners that are directly above the garage?

2) How does the price sound? I know it's a more expensive model, but that still seems high, even for a commercial product?
