TV to Receiver cables

Finally picked up big screen (Sony Bravia 46" LCD). I still have my Marantz SR-18 5.1 avr.....oldie but goodie. I have my Digital cable box and my DVD player plugged into TV via HDMI cables. My Marantz however will need to plug in (L/R audio) using RCA type cables.

I would like some suggestions on some good quality cables for this hook-up. I will need about a 6 ft length. Any advice is greatly appreciated. Thanks!
