Google or ebay for the missing parts to see what replacements cost.
You've gotten some really good advice in your prior thread asking about cost and 'value'. "What's it worth threads" really aren't going to teach you much. If you're interested in machines, there are tons of sites to educate and give you info so you can decide which machine is right for you and how much you're willing to pay. There are many threads on this site that you can read through about all the different models and the pluses and minuses of each.
