Hi Deaton: Exactly what type of problems have you been experiencing which has necessitated your X1 spending so much time in the repair shop? I was informed (from Bell Solton NY) that if I purchased an SD1 and warranty repair service was needed, that I would have to ship the keyboard 5000 miles (8,046 km) across the Country to New York, because local repair facilities in my area (San Francisco Bay Area) will not work on Solton keyboards. Your statement here certainly is a REAL concern to me.
