Hud-1 Excel file

I have heard of hud-1 excel file that you can fill out the first page and then excel do all the calcualtions for you. If anyone know where you can purchase this cheap let me know

Send me a private message. I have a friend that created a excel file to do that.

Shoot… a while back there was one online that you could fill out directly and click download and it would populate a HUD for you. Does anyone remember where that is?
