I was able to buy King Tut from one of the LQS that specializes in Long Arm Quilting. She has the Computorized Stattler Stitcher and says it's the only thing she uses unless customer requests or brings their own. Some times that won't work well and she has to discuss that with them. I paid just over $20. for 2000 yd Cone. I use it on both a 180 and 440 Bernina and haven't had a problem in over 3 years.
