(Asking a more generic question here) Why do I see this "I don't want to send it in" fear/paranoia so often? I recognize that sometimes the manufacturer will declare a unit OK when it actually isn't, but wouldn't you rather the peace of mind to know that the people who built it have checked it, and either declared it good (for the cost of shipping and perhaps a modest bench fee), fixed it under warranty (for the cost of shipping), or offered to fix issues not covered by warranty (out of warranty or out of scope, for a modest repair fee plus shipping)?
