the mother board went out on my long arm last year...boy did that cause some stress! especially since i was about 1/2 way through quilting a customer quilt...i called the company told them what happened...they told me what they believed the problem was...and had a 'reconditioned' mother board for $100 sent it to me in michigan from utah...i had it in about 4 days...
could you possibly get a refurbished one for your machine? or do you really just want a new machine? I have a viking designer one, and love it...
