buying used speakers

Thanks to all for for input. Let me be a little less general. I am seriously considering buying a pair of speakers listed for $4000 on this site. List price for the speakers is $7200, and checking around this is what they sell for. They are nine months old and said to be in absolute perfect condition. There is no feedback listed on this seller. If I do this I will use an escrow service so I can inspect speakers before the seller gets paid. Seller will send me close up photos and original sales slip proving age and ownership. I have had great luck buying and selling on this site so far, but have had no transactions this large. Am I insane?

No you aren't, and it sounds like you are just asking this out of curiousity only, and aren't really torn about what to do at all. Good luck, whatever you decide. What speakers are they, btw?

Jsbail- Sounds like you've done your research. I would make sure they are shipped in original boxes and insured. Paying by credit card through escrow service should protect you from most abuses. If you get original (not photo copy) sales slip and photo showing matching S/N, that would be additional protection. I understand your reluctance given the high cost; you might have more piece of mind by talking directly to seller on phone. At that price, he/she shouldn't have a problem giving it out to you. Let us know how the escrow service experience goes if you go ahead. I have not used one yet, but seller I am currently buying a relatively low cost item (<$100) wants to use one at his expense. Go figure. In sum, as Carl said, it seems as though you have made up your mind, and it also seems that you used all reasonable precautions.

Thanks Carl and Swampwalker for the input. I just wanted to bounce this off someone before I did this. I have spoken to the seller on the phone a few times. He told me where he bought them-so I called the dealer and he confirmed the sale. The photos look good so I am (excuse the pun) committed. BTW they are Proac 3.8's

You're welcome. Let us know how it plays out.
