Buying used or sight unseen speakers a bad idea?

I've purchased used speakers three times on this site. The first set was delivered freight across country and arrived without a problem. The second set I picked up, and they were just as described. The third set were shipped to me by a private courier and they arrived in excellent condition. They were like new, as described. Two sets were bought without an audition. I read a lot on these forums, and other sites, to make an informed decision.

Check their feedback to get a handle on whether you should purchase or not. Communication is the key. Ask a ton of questions if you feel you need to.

I haven't had any problems.

Hesson11 has a good point. See if you can call the seller to talk to him directly. I had one fellow call me just to pick my brain, to see where my head was at, before he made his decision to buy. He asked why I was using this item, and why I'm selling it now. We talked about how our systems started and how they got to where they are now. What we liked, disliked, and why. He was comfortable with dealing with me.
