Welcome to Librarium Online!
There was a thread on this, but it dates back to May 2006... and being almost 2 years old I'll let it rest in peace.
For all those who don't know what Armies of Immoren is, it's a free program that allows you to keep track of your model collection, as well as build army lists, and it even has a pricing function (as in: 1) build list 2) check cost 3) bring up the models you already own. This process will then tell you the total cost of the models you will need to complete the list you created). It's also actively updated to keep on par with PP and even has the updates given in No Quarter. Enough of my blathering, heres the link for you to check out yourself:

Good work Blood blade, this was an invaluable tool as I was starting to play WM, the ability to work out points costs and have EVERYTHING all in the one program is just awesome. ;Y
But I call to God, and the LORD saves me.
