I bought a Viking Designer I used, from a shop. The repairman is able to tell how many hours the machine has sewed and how many hours the embroidery was used. I love it. Having said that, shortly after buying it, the new machines came out using a jump drive. Mine takes the floppy. We weren't told this would change and we didn't know enough about it to ask. We had to purchase a converter, used, to convert the jump drive to floppy for the new patterns. Let the buyer beware.
