I just bought that exact card. It was 149.99 AR 10 days ago when I ordered it. It went up 4 days later to 159.99 AR. yesterday I posted my review and it was back down to 149.99, this time after a $20 mir. now it is up to 179.99 AR, probably because their sale worked too well and they started running low. I still think that is a good price, but it is creeping up closer to the gts 320 mb price, too. There is no way to know if newegg or anyone else is planning another price drop, and 179.99 AR is still good for that card, but I think I'd wait to see if they drop it again if you're not in a big hurry.
By the way, I overclocked mine to 681core/999memory on stock cooling. Unfortunately, I don't need that much power so I rolled it back to default for now, but it's nice to know it's there.
The rebate does seem a little more complicated than my 7600 gt rebate, but it's not really that much more complicated. You just have to follow directions and hunker down for the long wait.
