If you're comfortable enough to check some local welding repair / fabrication shops, you could find what you need for under $10 (maybe even free), but like you said; HD is easier. That still seems like a better deal than $50+ and you get the satisfaction of making it yourself.
Expanded metal is real easy to work with, and 12x12x12 (if you want bigger or smaller) isn't your only option the homemade way. Maybe find a drum first then decide the size of your firebox.
