I would love to sell on the other auction sites but they have NO traffic. I sell mostly home audio equipment and every single alternative had a miniscule audio section and nothing had sold. I checked as far back as possible...no sales. It's unbelievable. It seems people are only buying the higher end stuff now, vintage also. Less are buying items in need of repair or less desirable. But still if you find the right items, in good condition, create a good professional listing with great pics, you have the best shot with ebay, no question.
Ok, I didn't realize until now this thread was so old. It was only a few down in this forum. Guess it's kind of dead around here...
