Please define for us: "broke" the wheel?
Is it in two (or more) pieces?
Is it in place and not working?
Is it flopping around roughly in place?

Based on previous reports, odds are it's the last of those options. That's the standard thing that happens when someone drops the unit and it lands on the wheel.

I think it might be interesting to figure out how to repair it and post a D-I-Y guide for folks who aren't able to get support for it. If it's repairable, that is...

I'll say this in Krandor's other thread, too:

Sometimes in situations like this, one can get more with honey than with vinegar. Calling up and saying, "Yeah, I know it's past the warranty. But I know that you're a good company and you want to stand by your products. I really like the product and would like to continue using it, and I would like to be able to recommend it to my friends. Could you please make an exception in this case?" (And if the flunkie on the other end of the phone can't, ask to be escalated, lather rinse repeat.)

I'm not saying this would work, I'm just saying that it's the first thing I'd try in this situation.
