I purchased the machine as a used model. It is a Tiara, period. No II or IIIs after it so it's got some age on it. Not saying that makes it a bad machine at all. The dealer I purchased it from is not a Babylock dealer as my Babylock dealer did not have any for sale. They took it in as a trade and knew I was looking for a sitdown machine so they called me. I do have a relationship with my local Babylock dealer where I purchased my sewing machine so I will have them take a look at it. Only thing I have not tried is prewound bobbins; although now I really don't think it's the bobbin itself or the case as it's the top thread that's getting pulled under. I will eventually get this figured out!!!
