I'd like to know about the lamps you have on the machines.
I had an Elna - wore it out - really. Burned out the motor. Had it repaired. Burned out the motor. Had it repaired. Burned out the motor. Pulled it out myself. Had it repaired. They told me it had the wrong brushes in it. Had a helper taking it out. He broke the zigzag gear putting it back together. Haven't had the nerve to tangle with it since. The shop wanted more than a different one to fix it. Good machine though.
