I guess it depens upon model, it looks like Crown Point are part of the Japanese "deluxe" branded models sold under various names. They vary from all metal and smooth running models, to plastic and on the noisy side. You might find the same model under New Home or Janome. Don't underestimate a machine like this, now and then they turn out to be a gem. Some are not worth spending time and money on to fix up. I assume its a model that would need a bit of oiling to run as it should again, and maby a clean out of the bobbin and feed dog area. If you post a picture you might be given more detailed feedback.
Best of luck :- )
