I have the Huskylock 936 and absolutely love it! I make a fleece pieced quilt with it and it turned out great.
If you are new to using a serger I would suggest buying one from a machine dealer for the support. I have lifetime support from my dealer. I can go to the store anytime for personal one on one lessons as well as a free monthly serger class with the dealer.
I've had to call them a couple of times and they have been able to help me right over the phone.
Just my opinion. But I do love my Husky.
