Wire:

I find general purpose irradiated vinyl insulated,600V,105 deg C rated hookup wire from brands like Alpha, Carol Belden etc. to be fine performers. You have a wide range of gauges in both solid and stranded (all these brands are tinned Cu) and most colors. The ir vinyl stands up to the rigors of normal soldering w/o melting and looking bad. I tend to use 20 or 22 ga solid for low current apps and 18 for higher current apps like heaters. The 16ga is a little unwieldy even in stranded form so I don't use it much. Digikey carries Alpha and General Cable brands although only in 100ft spools. Actually, 100ft isn't as much as you might think.

Some like teflon insulated wire but I feel that it's overkill for most apps. It's also expensive and gauge and color selection is more limited. Digikey also carries the Alpha brand of this but with the 100ft minimum. Many DYI suppliers also carry tfe wire in much smaller minimums.
