Maybe even a vacuum repair shop or any small appliance repair ship. What about places like best buy? They do repairs. Course, sometimes its cheaper to go new, I found that out with a printer.
You might even look into second hand stores. I know the last time I was in a second hand store they had about 6 bread makers on the shelf. What brand is your maker?
Most small electric items are usually trash when they break down, like your printer. I bought an HP printer fax copier from my favorite pawn shop for $5 that had the owners booklet and disc. They had it on the shelf for a long time and marked it down to $5 on the discount shelf. I was surprised that it worked.
When I looked at my breadmaker, the first thing that came to mind was a sewing machine belt may work. I just called a sewing machine shop that has belts in stock, so one day I am going down there and see if we can find one to fit. I love to tinker with stuff, so I never give up very quick on something.
