I would go and test drive it and find out why they are selling when and who serviced it etc. Do you have a Bernina dealer close by for service if needed? Perhaps you could even arrange with the seller to have the machine looked at by a service tech to see how much use it's had, etc. It sounds like a nice machine even if you don't embroider but I can't help thinking "let the buyer beware" and I think you should be prepared to spend perhaps significant additional money if the machine does not work properly. On the other hand all the advice I've heard says buy more machine than you think you need, not less. I think you would soon tire of and be frustrated with the one with only 12 stitches. If you have the ability to buy a used machine from a dealer that would maybe be the best option as you would get some warranty and service.
