V) Gil Hebard Mount-INSTALLED
This is the Gil Hebard Mount. It is aluminum with plastic-knobbed lobe nuts. I have several of them that are over 30 years old and look new, so they are pretty pretty darn rugged.
I charge $52.00 for this mount, and that includes installation. Figure that the mount is available everywhere for around $35.00, add shipping of about $4.00, and then add the agony of installing it yourself, it may well be worth the money I charge to mount it.
