I have a Bernette (made in Japan for Bernina) that I bought in 1985. It runs like a jet engine and has an attachment that does rolled hemming. It's a workhorse, I use it constantly. I have NEVER changed the blade and that is after thirty years of sewing on fleece! If you are interested in serging, buy a good machine. Most have all the features built in but I would shop around and get demos before buying. You need to know what you will be doing with it. Bernina is the best but there are many on the market that are just as good. Don't go for price. I believe a serger for less than $200 will give you just what you pay for. A serger is a fast, strong machine and it best be built well to take the abuse it normally will get just using it. Good luck and happy serging!
