Reverb.com has their own guitar cables for sale that are amazing for the price. $7 for a 10 ft. cable and $9 for a 20 ft. cable - shipped! Solid plugs (that do not unscrew) with 24AWG wiring, foil shielding and cloth-wrapped jacket.

There's a video of them beating the crap out of one on their website. Check them out here: http://reverb.com/shop/merch

Perhaps not lighter but damn sure less expensive.
