I'm planning on getting a shuffle to use for running/working out/etc. Since I prefer the original colors to the pastel garbage Apple rolled out recently, I'm looking at either getting a refurb one from Apple (since they're only $49) or buying one off eBay. I looked on ebay and there was a lot of sketchy stuff for sale in the iPods section (lots of knock-offs, some of which could easily pass as the real thing to the untrained eye). Anyone have any experience with either of these venues? I don't want to be taken for a ride by some fly-by-night ebay scam artist but I also don't want to get ripped off by Apple.
