Which brand for wiring and where to buy?

Its not about how much I want to spend. I want good equipment at the best price. If there is reason to pay more for a particular brand Im all for it if there is a good reason. (Besides brand name).

Another question I was wondering. If the High output alternator I buy has a 4g output wire, why do I need to run 0/1g all the way to my trunk? Isn't it the water theroy. I can put a 12" pipe at the end of my water hose but its only going to flow as much as the smallest (most resisant) point? (12" pipe on a  1" water hose, sounds like what the kids do around here with their honda exhaust)

All the suggestions here are good.  Most of the name brand wiring kits and patch cables are great quality.  But IMO, for power wire there is no real need to spend extra money for a custom name brand kit unless you want the looks they provide.  Standard wire from Radio Shack, Home Depot or any electronics store (in the proper gage) is all I ever use for power and speaker wire.  I must admit I use Monster, Knuconcepts, Stinger and Streetwires (depending on available money) for my RCA and other patch cables instead of el-cheapo's but really only because I appreciate the more robust build quality they provide.
