Peter,
My two penny’s for what it’s worth.
I believe you have answered your own question. There is very little of the A&H equipment on the Second Hand market as it is sturdy, and generally reliable and has a long product life compared to its competitors. I purchased a QU and a SB and would only change the QU for an SQ as the premium I paid for the support, forums, and quality of the product have made the initial (I feel it is an investment in my customers and time!) extra cost worth while as my equipment just works!
Would I prefer A&H cheaper? Sure, as long as it wasn’t at the expense of product build quality, design or support.
Just my take Peter, however as the pennies become tighter round the world with increasing inflation I understand your difficulty.
