Service contracts are only a good deal for those selling them. Way back when I was a corporate warrior one of the things I did was price service contracts. These are far more lucrative than the product itself. If you pay $X per year for a service contract it's an odds on bet that you're not going to experience $X worth of violence in that time period.
You're always money ahead to work without a net and pay ad hoc for any needed service. Of course those selling service contracts will regale you with horror stories of how this or that person was saved from a life on the streets and perhaps debtor's prison because their machine exploded into a pile of greasy parts and their trusty service contract was right there tho save their ass.
What they don't tell you is the vast majority of service contract holders never even come close to using up $X of service per time period. Sort of like a lottery. For every winning ticket there's a few million non-winning tickets, Each one bought an paid for. With service contract, for everyone saved from ruin, there's thousands who are not.
If you can afford a service contract, you can afford service. The latter is always cheaper.
