If you're buying them on eBay, fine, but beware cheap, inferior quality pads which won't last or perform as well as reputable brands. I would certainly consider the OEM pads - they're not something you'll change too frequently (unless you're very heavy handed/footed!). I do agree, though, that OEM parts have a price premium out of all proportion to their quality at times - the Honda oil filter I recently bought for the wife's car left me feeling I'd been robbed!
