I must say - my experience with the US Parts line was very well. They called me twice to confirm questions and had a response invoice to me the same day.
While there are a number of pieces not in stock, the majority were there.
I was told that they put the items not on stock on a master request order, when it reaches a certain level, it is shipped from germany. Could be 1, 2, or 3 months. So if you are in a hurry, this might be a bad option. Although they do not attach names or invoices to that master, which I think would be the pinnacle of Customer service.
Bill: I only have a few items I am still in need of, will send the list through in the next day or so. Hoping to have this main piece restored by Christmas for my son.
