Declined TF2 item price calculator

[Quit TF2]

So, I've been trying to work towards the Australium Grenade Launcher. I was BLACKwondering if anyone knew about a site or program that can view my inventory, allow me to take items from it and put them onto a grid or something, and have it calculate the price in keys.

You can go on backpack.tf, log in, go to your inv, hover over the items and wriite down the numbers, calc, done.
