Just looked at an old order and I paid $70 for a 25' set of 0 gauge cables. Big heavy clamps, flexible in the cold, etc.. pretty nice set.
They are great for jumping the occasional tractor. Engines spin over way faster compared to the lighter gauge stuff.
If you start getting into $70- $100 bucks, you might be better off buying a jump starter pack. I carry a NOCO GB150 in my service truck. Money well spent, but they even have some good ones for a lot less.
