I've been wanting to purchase a surger for awhile. A friends Aunt passed away and they had two machines for sale. One was a Huskylock 936 serger. They were asking $500.00 for the machine. It's about 5-6 years old. My friend brought it home for me to see and try out. I have to learn how to thread it first. Do you think it is worth this much? We were offering $300.00 Can you let me know what you think about this? Thanks.
