Given they are not perfect (some have rear camera problems, some with a bit of debris under the glass, etc.) but they're returns for the Power button issues that have been fixed. I think they'd hypothetically go for $175 each***see edit, based on what can be found on eBay. But that's only if this person decided to try this hypothetical story.
***EDIT: I looked on the eBayz.. these hypothical devices could go for between $100-$200 depending on size.
