I've got nearly 3K points, all of it for about 450ish, maybe... I forget the exact price, but it wasn't too bad, especially since I used call in order at 20% off with free shipping over 80 dollars or so. I also used eBay a bit, they've usually got some good deals on stuff; got a new Nightbringer for 20 (including S&H) So, yah, I'd say Necrons aren't too exrensive. @ Battleforeces would be a good place to start, like Karmoon said.
