Source of all flat cost weapon and armor enhancements?

[skunk3]

Is there a source of all FLAT COST weapon and armor enhancements, with sources?

Thanks

My treasure generator has a section on weapon enhancements, and lists cost (either the + bonus or the flat gp cost) and source as well. As far as I'm aware, its every one that has been printed.
