The one I posted is significantly less. It's the only reason I bought it. It's definitely not $50 worth of wire, but for $25 it's a nice kit. It's really almost worth it just for the box. Yes, the wire actually IS better. At least it's better than the other junk I have here. Thicker insulation, perhaps? I'm not sure why, but it's definitely stiffer and easier to work with than typical cheap jumper wire. Maybe it's a slightly thicker gauge? It could be that my other, cheap, jumper wire is just particularly crappy, and that the 3M stuff is normal.
When it's all nice and organized in the box, things go so much faster and easier, that's for sure.
