Where can I get my Sunbeam Mixmaster Heritage #2351 Stand Mixer repaired?

Ever since I purchased my Sunbeam Mixmaster Heritage Series Stand Mixer( model # 2351) the motor is very noisey! It seems no matter what speed you run it at the Mixer sounds like athrashing machine. Mixer has hardly been used since I purchased it about 21/2 years ago. I called a small appliance repair shop about fixing it, but they would have nothing to do with that model and I was too late to hve it covered by warranty. Know where I can bring it or maybe I can fix it myself. Thanks
