One quick question: the Singer 206 -- buy or pass? Good condition, cabinet, seller just wants it gone, heaps o' attachments. I know about the needle and odd setup but also about its historical significance. Apparently there are three versions of this machine at last count. Any experience with sewing on a 206? I've read both rants and raves and since I have no experience (but I do own a 319W and I like it very much), I'm wondering what you folks might think.
