Dave,
Option #1
The least expensive option would be to use what you already have, $0 investment required, you already have an opener that works.

Option #2
$70.00 = 1 tank of Premium, just don't drive anywhere for a week and it pays for itself

Unfortunately like everything else, any add-ons/enhancements always cost money.

I bought mine 4 years ago, everything has gone up.

Gone are the days when 2- bits would get you a cup of coffee


(Sorry for the Smart *** reply my friend, but I just couldn't resist)

Hope you're day is a good one
