I`ve bought a load of the jumper leads just for convenience, which were about $6 but that isn't likely to bankrupt you Smiley
Single core wire tends to bend as you plug it in once it's been used a number of times.

The second option come from a couple of rolls of telephone hookup wire
The little "V" shaped wire stripper/cutters suck IMO for small wires
