fester,
I did the same thing to my M$ stick, but with coffee.
What are your symptoms? Mine were a blinking red light, but the stick worked in windows, just the force feed back motors were dead.
If your's is the same, I may be able to fix it the same way I did mine, by replacing one of those "itty bitty" little chips inside known as an H-Bridge driver chip.
If you (or anyone else) still have a 'dead stick', before throwing it away, give me a shout and I'll see if I can fix it.
