Yeah, it all depends on price, and wether or not you "mess" with your hardware. If you plan on just using it at stock speeds, then I'd go with the cheaper one, most likely the 9600 pro at <A HREF="http://www.allstarshop.com/shop/product.asp?pid=8694&sid=0REHEL2EVMPG9P88QG7KA2RVB4249DXB" target="_new">$83</A>. Both cards would perform similarly at stock speeds, both can overclock well, but IF you get a successful unlock to 8 pipes, then the 6200 is a killer card.
