I have resisted so far but I'm starting to want a FW too. Sigh! A couple of the ladies in my guild bring theirs to classes and they're such charming little machines. Not good if you want to be left alone, though - they both end up with people coming over to check out their machines every time! (Our classes are held in a local sewing store that doesn't have a separate classroom, we're just off to the side, so shoppers often pause to see what we're up to, and gravitate to the FW ladies.)
Although if I stick with my cast-iron machines, I'm bound to build up some good biceps...
