Closing Statements

I was inspired to create this guide due to the fact the workbench only shows upgrades the user has enough skill rank for and the next mark up. I found this to be annoying when planning on how I will upgrade my items and I hope others will find this guide to be helpful as well. If enough users find this guide useful I will create similar guides for the other upgradeable items.
