ebay wants to advertise as being a site where you can get cheap stuff, the lower the startingbid is, for buyers it may seem cheaper. Quality stuff is another matter. When i buy something, i buy quality. i usually buy from my favourite sellers list, every time i make a successfull purchase, i add that seller to my favourite sellers list and when i am searching for something then i search for that item from my favourite sellers list first and if they don't have it, then i buy from some-one else.
Me personally don't look for cheap items, but for quality items, but others usually look at the price. and the lower you start, the lower it may seem for the buyer.
