I went back to re-read the original post and it seems I read it too quickly the first time. I thought the OP wanted an opinion about warranties (and yes, if you want to split hairs I do understand it's tantamount to a "service contract"). In any event, I stand by my original response which is clearly an opinion that the OP can take or leave. How about taking a chill pill!
