I had a zero feedback bidder buy a $2300 kit from me last month. He had zero feedback from US ebay and had another ebay account in China. Second nice kit I sold to someone in China. I have had a few 300 plus feedback bidders back out after winning an auction.
I've seen so many auctions where a 0 bidder wins & then the drum is back up fairly quickly. That's all I'm saying; and I'm not stating you're doing this. When this does happen there are usually a ton of bids.
Good luck with listing!
