i know this probably ain't what you're looking for, but i'd recommend pchcables.com
After a quick check i think it has what you're looking for. They're a local company to me (PNW region) and i had a great experience with them. I needed a firewire cable for my ipod and retail stores are asking ~$30... i got it from them for about $4 or so..
Pat (who i guess owns the site) e-mailed me after i left a comment in my order box about a slightly cheaper option for shipping (i was complaining that cables should NOT cost $8 to ship, and he helped me out. Good guy, i left them a good reseller rating.. i dont know if it showed up yet
