For you IG players, I found this cool Excel IG army list calculator from Warseer. Check it out at this link http://www.warseer.com/forums/showthread.php?t=196321. Basically it'll allow you to calculate your desired army list, minus the hassle of refering to the IG Codex for point cost. This excel format can be utilise for other codices, as long you are willing to create a new formula and input for that specific codex. It's pretty intuitive, check it out.
