The best sources for cables are:
"1. Blue Jeans Cables (much cheaper than other people selling the same quality materials for cabling & very upfront with what is used to make their cables)
www.bluejeanscable.com "
"2. PC Cables (best prices, quality cables with cheap alternatives)
www.pccables.com "
"3. RAM Electronics (nothing but praise on this company as well. They are a forum sponsor so maybe that will influence your decision, but if you want to spend the least, even RAM sells the same Component cables with Canare connectors as BlueJeans Cables, but for a noticably higher price, yet nothing near the prices of BetterCables)

This information was quoted from new member "onthejazz" in the Official Sanyo Z3 thread, but pretty much summarizes what I, and others, have found. Do yourself a favor and stay away from the very cheap cables that PC Cables sells, even if you have to bust your $40 limit per cable. The cheap cables are just a waste of money. They're cheap because they use very poor quality parts that don't have the bandwidth for video signals. This becomes especially critical for cables that are longer than 10 feet.
