I've only checked a couple of websites: newegg, mwave, googlegear and provantage so far, if they don't have it then I don't really want to trust websites that I'm unsure about but I'm about to look even further. My z560 rma is on backorder until the middle of april...how lame. I'm thinking about just getting the 641's so I don't have to deal with this crap anymore. Well, can anyone point me to the 641's online?
