I would be leery about spending so much on eBay for an older used embroidery machine. My Brother PE770 was purchased new for $700.00 and later I added a hoop set for $99.00 all from a seller on Amazon.com.
I would check out stores in your area, some may have a machine in price range and you will have a place to take your machine back if problems exist.
Buying an older machine like the one you posted a link is tricky. You stated it uses floppy discs, software maybe hard to come by. Most newer machine use a USB port for extra designs via hooked directly to a computer or use of a flash drive. I would try to find a newer model, you will be happier in the long run.
