I have a 301, and it has become my workhorse. It is sturdier than the FW, with steel gears that make it able to sew through any thickness, even multiple denim layers and faux suede bags. I have used a friends FW, but not often, so perhaps I am biased. But my vote is the 301. Oh, and I live in Vancouver, so I know about dark rainy days! My 301 is black, but a good lamp on my sewing table takes care of that.
