I have use ebay for collecting science fiction and anime/manga items (no, not bootleg, or porn stuff) for over 200 hundreds times and because I was CAREFUL (checked the seller's feedback before I bid and stayed in contact with the seller), I have not once really had a problem.
I got taken for about $75. After pursuing the matter for a day I dropped it. I was losing money every additional minute I put into it.
In any event, good feedback rating or poor feedback rating, eBay can go pound sand. I shop on-line now through one source that includes auctions along with links to manufacturers, retail outlets, and service providers. Plus, I'm given a rebate for all my purchases and for purchases of people I refer to the site. Any problems and I pick up the phone and speak LIVE to a real person who actually helps me.
