Pretty much use eBay for buying. Selling got to be too weird, with fees being raised, taxes collected, then hey PP too. I gave up. For buying, it is really a joke to read that the unit has been tested and works 100%. I know better that this is BS. Fortunately the component that I am looking to buy will be completely rebuilt and it doesn’t matter about working order, or up to spec crap.
If I want to have an interested party offer to buy my equipment, then this is the place. Less tire kickers, generally more knowledgeable about the product, and hopefully don’t think that this site is a yard sale.
Packing properly is a concern for both buyer and seller. Nobody wins when a product gets damaged in shipping.
