Where did you find refurbished ipads? Apple claims they aren't selling them yet...
its not a large discount. Id almost rather buy new and ensure that i don't get one with any scratch marks or anything.
I'va had a number of refurbed iPhones before and they were always in perfect condition, i'm sure they replace all the external parts to make sure this is the case. Apparently they're even replacing the batteries in these too, so it's very close to getting an as-new one.

I never buy refurbished electronics. You might save a few bucks, but it really isn't worth it. Did a couple of times before and regretted it.
