I have a pair in my home theater along with a C50 center channel. I've had to replace a few drivers over the years, but they've given me over 20 years of service and still sound great. I've upgraded everything else in my theater more than once since I got these, but these speakers are here to stay until they break and I can't fix them. I haven't had a problem with them in over ten years, so perhaps the replacement drivers resolved the reliability problems.
I've had good luck selling on us audiomart. In the Seattle area, you might also have some success on Craigslist which would avoid shipping.
Recent sales of these have been in the $1500 range. For that price, it would be hard to find a better sounding speaker.
