Thanks for your suggestions. First of all I have to say that I am not located anywhere near the US or Canada, which means even IF one of the sellers would be willing to ship something my way, I'd face horrendous shipping charges as the Ninkas aren't only huge, but also heavy. I'd also have to face custom charges which would immediately destoy any financial benefit I had when I bought them.
Then again there sure must be sites like audiogon.com that are better suited for me and the country I live in.
The worst thing I have to say is that I yesterday missed out on an ebay auction for a pair of NEW Ninkas that went for 1000$US, which is even less than half the price they cost new over here. I waited for the auction to end more than 8 days and when it finally came to an end, I missed out on it - nice I just lost a huge amount of money.
Sadly there barely are any Ninkas to find on ebay, which means there is only very little point in waiting and hoping for another pair to surface...
Well, again thanks for your suggestions - I'll see if I can somehow manage to find a nice deal for the Ninkas, not having to pay full retail...
