The Singer 700s will take black or white top hats. No one wants a 700 machine, though, unless it's free. I don't know about the 600s, (the local OSMG said to get only the 600 or 603 - he said they are great machines) as the only one I've messed with (646) has no cams. The black top hat are easy to find (I have plenty of white ones, so never looked for them). The flat black ones are available but are usually sold on ebay as single cams for about $4.00. I lucked out on shopgoodwill and found a group of accessories and got about 30 flat cams, a couple of buttonholers, a monogrammer and a bunch of plastic 66 bobbins for about $30.00. (I really wanted those cams for my 328).
I've kind of been watching for those Gritzner cams, as I have two of those Kenmores and one of the Whites that are project machines. I'm not sure I would recognize them if I saw them, though. I've been sorely tempted to buy that $100.00 White on CL here. It's 100 miles round trip and I'm not too gung ho on that. It looks like a really nice machine and it's supposed to work. He says he has all the original accessories and manual. There's not much demand for "not-singer" vintage machines here, so it's been available for a while.
