Ya, I would not want to invest that much money in an Elecraft and take a gunshot approach with accessories.
I pay for what I get. And… I have some exceptional Elecraft equipment on the desk, in the shack, in the go-bag and one currently at Don’s place. I always take the approach to buy what I can afford but sometimes… I do spend more to get something exceptional. Wayne, Eric, Don, thanks for all your help over the years and for building exceptional equipment, as well as exceptional support.
