help! looking for good no-stretch rope for low $

any info given will be helpful. i am in the market for a good quality no-stretch rope, at a good low price. anyone, know of any great deals out there? i have looked on ebay and have seriously considered the power core rope (Bullet's vesion of the accurate jacket) from Bullet Ski lines and the Chronic Cable from GethighSports.com. are these good options?? how important is spectra? i've also looked at Hardline Stryker and Shoelace... i've been boarding for a few years now, but just never realized that ropes made that much difference. any and all info i can obtain will be useful. thanks and God Bless.
