Just a follow up to my last post. I got my Nobblex Pro 6/150 back today from Siggi and it is in great working condition. Service was very fast as total time to get it back from the time I put it in the mail was less than two weeks. From the US you can ship to a P.O. Box in Washington state and he picks up and ships back from that address. I would recommend Priority Mail for shipment.
Nothing bad to say about other repair services but if you have a Noblex that needs repairs Siggi is the man to send it to IMHO.
