However if you want sell Chinese junk, which is either fake, or has programmed obsolescence built into it, eBay is the place to be.

I sell very successfully on ebay without listing any fake, junky or obsolescent items as do many other people. Ebay is also the first place I look for rare books and replacement china when I am in Aus.

For a very valuable or rare item most people on the boards advise people to look at a B&M auction house, horses for courses but even with a network of clients no auction house is going to have the worldwide exposure that you can get listing on ebay.
