I find this whole thread alternatively entertaining and troubling. $200 to fix a spoke? Seriously? Back 'n the day, a replacement spoke would cost $1 and to install and re-true would take less than 30 minutes.
Anyway, if you take the shop up on their offer, how do you know that they will actually ship the wheel back to Mavic, versus repair your wheel and flip it? Plus sell you a new wheel at a significant mark-up.
