I don't think it's bad to look at color. It caught my eye. I was also looking at a Singer, I think 403? Slantmatic, which was kind of a yucky tan. I like Pink better, but I also looked at a turquoise machine, and a couple of green ones.
I think the guts are most important, but if you can get what you want in a pretty package- what's the harm? Billy gave the thumbs up to several I was looking at. The other was a Brother zig-zag on ebay that is black and pink. (Even more fabulous in its styling) which I think ends tomorrow. Lots of good buys for the 50's/60's machines.
