Hello, and welcome to our little corner of the net.
I would suggest you keep an eye on Ebay, Craigslist, or Kijiji for one that someone is parting with.
Or, unless this one has great sentimental value, purchase a new one. Sears has a good 2 base combo unit on sale quite regularly for about $110.
Put yours up for sale... someone might need parts and then you can use what you got to offset the price of a new one.
Sometimes I wonder whether the world is being run by smart people who are putting us on
or by imbeciles who really mean it.
