Do you know what, specifically, is wrong with it? If it's just the amp, a local tech might be able to breathe life into it for much less than Sennheiser would charge. Even if you have to have a couple of transformers rewound or customs built, it wouldn't be that bad.
A burned out driver or two might not be worth it - the factory might charge a pretty penny to repair it.
So I'd investigate further. If the cans are good and you can sort the amp locally, it might be worth it. Look for someone who restores tube radios and TV sets - those are an order of magnitude more complex than a headphone amp, so it shouldn't be much trouble.
Also, you might want to poke around for someone local who restores Quads and other ESL speakers. They might be able to replace the diaphragms for you.
