I have a viking 905. Love, love, love it. I don't do a lot of serging so this has been perfect. Quiet to run, wonderful stitches and it has a removable piece so you can do cuffs or pant legs. I bought it for $200 on craigslist, actually from someone who used it extensively to make activewear for her family. I have had it for maybe 10 years and it has never given me any trouble.
