I think it depends on WHO is doing the refurb. For example, apple refurbs their own products and usually changes the case so it looks brand new. BUT I've also seen third-party apple refurbs that look awful and are scratched etc...

For the most part refurbs are ok, just check the return policy, and waranty. Most creditcards offer a double waranty too. So checked with your CC.
