This site has some great information about the 400 series of machines:

Here is a comparative list of the stitches that the 401 & 403 machines can make. (note: the 403 uses only the external cams)

I have this same list Debbie. I used it to get the rest of the set for my 403. If you want, PM me the cam numbers you do not have. I will get in touch with the gal & get her pricing & contact info for you.
