Beyond economic repair

[ewx]

How do you decide when something is beyond economic repair? A while back I bought a rather nice lens second-hand for £400; new it would cost £690 (maybe a bit less depending how much time I spent shopping around). Since then the AF motor has failed and I've now put it in for an estimate to repair it.

My current thinking is that £200 seems a sensible limit (being half what I actually paid for it and still keeping my total expenditure less than having bought it brand new in the first place). Any other views?

I thought someone would ask l-) 135mm f/2L.

Ouch. I'd have been very tempted to leave a macro lens as MF-only but not that beaut. I think the price you'd be prepared to spend on it to repair also depends on whether you could afford to make the purchase afresh now. So how much would you sell it for in broken state?
