Pulling the trigger on pricey equipment


I have the opportunity to purchase a somewhat expensive pair of speakers from a private seller on Audiogon. His feedback is around 30 and mine is around 160. I have never purchased anything this expensive online privately. The speakers will have to be palletized and shipped freight insured. My angst is in I'm sending a lot of money upfront with the hope of receiving the speakers. Are there any suggestions regarding payment (maybe 1/2 upfront and 1/2 upon delivery) or best way to safeguard my money and alleviate some of the emotional stress in this transaction. Is Paypal my best option?

I agree with Roxy. Speaking on the phone is key, getting a sense of confidence. Reading the comments on feedback too. I've performed transactions over $10k on audiogon before (both selling and buying). The most expensive purchases, however, were from dealers. I think the 50/50 is reasonable, though I've never done it or the escrow (also reasonable, especially if you pay the Escrow fee). For really expensive deals that I've fantasized about, I have though about flying out and overseeing the deal in person. Palletizing is great, and not too difficult with a good shipper (e.g. Pilot Air). I've received 2 pairs of Avalon speakers in crates palletized - very little worry about damage.
Feedback rating and comments go along way. However patience and a tank of gas makes for the best feeling of confidence in a high priced private deal. From a dealer I would not be concerned.
I wired $30k to a guy in Singapore for a high end turntable. He had very good feedback; much more than 30 but still a lot of money to wire to a guy I didn't know and overseas to boot. 4 days later the turntable arrived via DHL as promised. Best part is the shipping was included. Go with your gut after a long conversation, or fly out and watch them be loaded on the truck! Might be cheaper than the escrow service and more fun!
I have never had a problem on Audiogon. Everyone has been courteous and efficient and no deal has gone sour. I really do believe if you are polite and do what you say, when you say, you are more likely to be treated in the same way.

What you have to watch out for, is an A/C being taken over by a fraudster. That happened to me on E-bay about 10 years ago, my password was changed to shut me out and about $1000,000 of kit, including BMW's, Audi's, high end speakers, put on sale with a 3 day auction. Luckily I jumped up and down and waved my arms and eventually E-bay stopped the transactions.
Yes PayPal is your best option ..anything else would be complete folly. Just make sure you send money to a recognized PayPal name and address.
