the viking 500 was a very good machine for it's time-mid 1990's. lots of stitches, and a nice buttonhole to it. i have it's little sister, the 350. i LOVE the machine...it's a true workhorse, and i bought a viking 140c this summer. I think i know where the manual for the 350 is....if i can find it, would you like me to make a copy for you and mail it to you?
