My first quilting machine was the Viking Quilter ll, bought from local dealer. When I brought it in for tune up after first year the repairman really messed it up. Finally found a dealer 1 1/2 hrs away but he fixed it so it was better than new. Then my A card became invalid or would not work. This part is no longer made by Viking! So I bought a new machine. But I did find that exact card on eBay for $40! Recently I brought the machine back to my repair guy for tune up. So now I have 2 machines in good working order at least for a while!
