99% of the for sale add's are over priced. 75% are way way over priced...so much that you cant even or don't even what to start a negotiation. The others you try to start an honest fair negotiation with either never respond or get all pissed off.
I just recently sold an entire 7.2 home theater system...not the highest grade stuff but really good...Klipsch Ref7 speakers, dual subs, 7 large speakers, Da-Lite screen, 8 theater seats, video processor, middle atlantic racks, Oppo, Marantz processor and more. Sold it all in 3 weeks max. Priced it right to sell. Its gone out of my life, not in storage and I've moved on. It was very easy no drama sales.
I am currently looking to build a "Listening Room" in my new home. For fun I am buying all used gear if I can find what I like at a fair price. So far...ZILCH...I'd rather pay a few more dollars and get new. People think there stuff is worth it's weight in gold and some sentimental family heirloom! Its used electronics guys...geesh!
