I think buying points is money well spent. I think hiring a BC sheep outfitter is worth every penny, because that gets more expensive every year.
By all means, play the draw odds. Just realize you are only 1% more likely to draw the 2% tag than the 1% tag. So you may well never draw either in MT (although the new squared bonus point system "should" help).
Come to think of it, I agree with Husky. I don't think anybody should put in for 680 or 482. Really ... tell all your friends.
