I don't know what condition your machine is from the fall but you mentioned the feed dogs. These are sometimes easily replaced on some machines, and very cheap to replace. Call a sewing machine repair store and ask for a price on the feed dogs of your machine. If that's all that's wrong with the machine, you might want to consider replacing them. Some machine feed dogs are only two screws, take out and screw them in. Another consideration is to watch the thrift stores or Craigslist for a machine if you don't want to spend too much on a machine at this time. Just make sure the bobbin assembly is in the machine and the wheel turns freely.
