Have a Viking Designer LE w/embroidery unit and love all the features: needle up/down, needle hover, speed control, settings for fabric selection, auto thread cutter and needle threader, fancy stitches including 1/4" quilting stitches, many feet, bobin notice, memory for designs and the website and SOS tech support and updates for your computer and machine. Most dealers give unlimited free lessons on how to use and some even have free clubs to aid in the learning process. Also, if the dealer you bought from goes out of business or you move, my experience is that the dealer you choose can take up and continue to teach you. Also, most of the dealers have a certified repair person to take care of your machine and if they can't repair it, then they send it to Ohio. I also have a 936 Serger. You can't go wrong with a Viking.
