Ended up with the Genie Excellerator, the cheaper of the 2 units (didn't
need the extra controls). Installed it myself, replacing a Chamberlain
chain drive system.

It's 10x quieter then the chamberlain. The high pitched whine is rather
annoying, but it's quiet otherwise. I'd be curious to here how much quieter
a belt driven unit is (Chamberlain Whisper Drive was my other choice)

A bunch of people recommended the Genie Excellerator as a great overall
unit, and the speed of opening is very impressive. I won't have to sit in
the driveway anymore to pull into the garage.

I live in central, FL, so cold winters so any potential issues with the
screw drive are not a concern.

I need to replace my chamberlain chain drive. 1/2 HP is enough for my
metal 2 door garage door.

I want it to be quieter, so that means belt or screw. Don't have
preference to either. $200 is my spending limit. I want to be able to
get it from HD/Lowes/Sears. I've been pointed to:

Chamberlain Whisper Drive
Genie Excellerator

I assume the basic features (2 control, optical sensor, smooth
stop/reverse) are all the same. So I'm curious about little extras
(disabling remote, backup battery, etc). And just the general overall
quality of the unit.
