Ok- I took all the advice I have gotten over what it is I really should be looking for in a back-up heavy duty machine. It seems like the consensus is a 15-91 will sew multi-layers and handbags with no problem at all.
I've also had a couple of people recommend a 201??
(Secretly, I really, really want a 15-125 because I love love love the mint green, but can't justify the boost in cost. Damn it.)
So, what does the 201 get me that the 15-91 doesn't. Or vice-versa?
You guys rock!
