Audio Eden & Lack of Response - Anyone Else?

I have tried since last weekend to get a response from the Canadian retailer, Audio Eden, who is offering a used Nait Naim UnitiServe. Calling them occasionally got a response to call back later. Their terms were onerous; quoting in Canadian dollars only, refusing to use PayPal and wanting to impose a 6 1/2% tariff to ship into the States. That one really steamed me. Since when were tariffs applied to used goods? Near the end of my frustration when I couldn't get any response to my emails I tried to call them. Apparently they are a 2 man shop. The fellow that I could get on the phone always deferred to the other guy. I tried for three days to reach him but never did. I'd beware of these people. All my other Audiogon experiences have been very positive. This is the lone exception. I'm now glad that I didn't buy from them. Had I had a problem I seriously doubt that it would have ever been resolved.
