I made some phone calls, and no one around here can repair it. Apparently, Sunbeam doesn't supply parts for the model I have. And considering how heavy that thing is, the shipping to send it in to the manufacturer would be murder (that's assuming it's worth it to get the thing fixed).
I've been doing research online, and so far the Kitchen Aid brand seems like a good bet for a replacement.
Anyone with a stand mixer have any recommendations?
