I use JW Audio, which are 12 gauge OFC pure copper. They sound strong and clear and I think I payed around $80 for an 8' pair. Super performance at real world prices, if your not one who has to have silver in their set up. They are a bit stiff and stubborn to install so you probably wouldn't want any woman or children around when doing so.
All the best
