Where can I get my blender repaired?

About a year after I came to Taiwan, my Oster blender gave out. I guess it was a dud because I’ve always had good luck with them. I bought a Braun from CCC, but it died a few months later. They replaced it with one which had been used before (probably returned and not repaired) and it lasted a couple of more months. I had the part I think my Oster needs sent from the States, but I don’t know who can repair it for me. I use a blender every day for breakfast shakes, and I really miss having one that works! I’d even buy a new Oster if I knew who sold them (a friend said she had seen them but couldn’t remember where). Help?!
