Hi, I've decided to get the current rMBP because I don't want to wait for Haswell and of the awesome price difference when buying it refurb'd or on ebay. My question is what do you recommend between buying one on ebay versus the refurb store? I could theoretically get an educational discount at the apple store but would have to pay tax. Ebay will have no tax (but likely shipping) and can likely get a used rMBP for several hundred cheaper than the refurb store as well. Not sure where to get it from now... Thanks.
