A PC drive won't read Xbox game discs. A PC drive also requires some alterations on the interier to get the fit right. It's not that it can't be done, but in most situations both of these are very undesirable consequenses.
Samsung and Phillips drives, with Samsung being the better choice for most people, are the names you'd want to go with if you buy an ebay drive. I just got a whole new Xbox for $35 so I don't know it's worth it as those drives cost about that.
