Singer 300, 400, or 500?
I keep reading about these great machines and although I covet the Rocketeer, I have heard others say they would love to have (or do have and love it) a 300 or 400 series machine. Is there a way to rank these either because of what the machine can or cannot do or is it just a matter of personal preference? Yea, I know, like I actually need another machine when I am not even using some of the ones I already have. But still, just in case I "accidentially" come across one of these Singers I should be informed, right?
