Check out HiFi Shark, it will show you all of the used sites, current and past, so you have an idea of what prices are.
Also, there are some AZ internet dealers on Audiogon (sade, mlmusic). You could ask what they would charge for a new pair of Satori’s, I bet it would be under $500.
BTW, your 4 takes are pretty accurate. Only issue I see is that number 4 interferes with number 2.
If you choose to go The Cable Company route, you will NOT be paying used prices.
