Go to EBay and look for your particular machine. You may be lucky!
My son in law dropped my daughter's very expensive camera in the ocean a couple of years ago. They happened to tell a friend about it. The friend went on EBay and found the exact camera at a fraction of the original cost. The friend also was able to get the camera and do the work to make sure it worked like new since that is his expertise.
If you find the machine, you could have someone work on it for you to "reconstitute it" if it needs anything. Also, on EBay, the seller must tell you the truth about it or you can send it back to them.
I know that shipping expensive on heavier items but I did buy a Brother machine on EBay a few years back and the seller paid the shipping. Perhaps you could work out something whereby the seller would pay the shipping if the machine was not what he/she siad it was.
Anyway, it is worth looking into UNLESS you are going to invest in a Bernina or something. However, it sounds like you were in love with that machine.
