An excellent, and cheap reloading bench is a solid core wood door. They can be found cheap at construction material surplus outlets. I might have paid $30.00 for mine. It's oak.

You must pre-drill any holes in it to mount anything. It's usually already "finished" in a hard lacquer/oil finish. And you can cut it to size easily enough with a mechanical saw. Or a handsaw if you want to build up your arm muscles!

I have two of them. One is my reloading bench and another is my standard tool bench in my "Doghouse" (workshop).
