You could replace them yourself. Autozone sells ramanufactured axles for my car (95 gsr) for about 60 bucks a piece. And they have a lifetime warrany, take em back next time they bust. There will be a core charge of 55 bucks a piece. Even if you break them again you dont have to pay for it.

*edit* dont know about the ebay shafts though, and i dont know if shafts differ from manual to auto transmissions. But that will be about the price for the shafts.
