My latest acquisition is this 206K25. I have not had time to CLA, but it looks very promising. I studied and asked posters about the 206 and have pretty much determined the 206, 306 etc were early ZZ machines almost too complicated for the household. That's a challenge I accept. Will keep you informed. I was lucky to get the few accessories, such as the odd 206x13 needles which are reported to be expensive and difficult to find. Compared to 15x1 needles that may be true, but I've seen them offered an many sites.
