radioshack and ebay are always your best friends. radio shack if you have one close to you and dont want to wait for shipping and pay a little bit more, ebay if you want to get CHEAP stuff and dont mind waiting. the cheaper the item the longer it takes to come because it comes from far away places were they make them or get them for almost nothing (unless you live in hong kong or china). you can always pay a little bit more on ebay to get someone selling in your state. its like a few bucks USD for one hundred resistors and the more you buy the more cheaper it gets per resistor. the BEST kynar 30 awg wire is always on ebay. dont use anything else. others will work but the one on ebay is the best. the rest are less quality and there insulation is made of cheap plastic. the ones on ebay are made out of a shiny quality plastic. (if you get the right one) and those are a few bucks USD for 30 feet.
