Laptop Firewire cable (i.e. 6 pin to 4 pin)?

What is a high quality, inexpensive laptop Firewire cable (i.e. 6 pin to 4 pin)?

none

cheap cables are not high quality
high quality cables are not cheap

so you ask for something that does not excists

btw
i should go for bandridge

What do you want to use it for anyway? For 99.99% of the things this cables can be used for, the cheap ones perform great…

Connecting a secondary hard drive to my laptop via it’s Firewire conection. Hard drive to contain mainly WAV files.

Are these high quality?:

Also, is there any performance difference (theoretical or practical) between a 3 ft. and 6 ft Firewire cable?
