I have the 905 AND the 936, which is computerized. I use regular Schmetz 80/12 needles in both of them. I love the 905, never had any trouble with it. It HAS been discontinued, but in my estimation, only because it is a good machine and well built. My Viking dealer told me the newer Viking sergers are not made by Viking and are not as well made inside. So keep the machine and buy a bunch of Schmetz 80/12needles and you will be good to go for years to come.
