I'm a little nervous about spending a large amount of money on ebay. But I've been thinking about purchasing a Shun Classic cutlery set and the ones on ebay are about 60% of the same ones from Williams Sonoma and BB&B. They are all advertised as New in Box. Anyone familiar with this? I guess one pretty big downside would be you couldn't return them, but would Shun honor any warranty directly? Thanks for any input.
