Carrot, not stick, I suppose.
And I don't know how I can be clearer than in the comment you are replying to: "My point was that it reasonable to be reluctant to spend $200 to $250 to replace a small component of a device that is only worth $300."
Which part of this sentence is unclear?
Your Porshe analogy is not appropriate. If a Porsche with a working gearbox is worth 35k, then yes, I'd be reluctant to spend 30k on a gearbox alone.
We are now rolling out my tooling in the company so everyone can forget about the boring stuff and just focus on the business logic. There is resistance as this is going to cost jobs; we don't have infinite work to do and this is much (much) faster.
My point was that it reasonable to be reluctant to spend $200 to $250 to replace a small component of a device that is only worth $300.
This was in response to someone who claimed the OP should just sell it if he didn't want to spend $200 to fix it - because it originally cost $3000-$5000.
