Who makes the best battery jumper cable? Ones around here in the auto parts store are almost useless. I had a set made by Associated that were really good but grew legs when I let a relative borrow them (long story). Anyway, want the best I can get in the $150-200 range. I don't have the skills or the patience to make a set from welding cable. Would just as soon buy them and be done with it. I think 600 amp and 20' min. will work OK. Would like for them to be 100% copper wire.
