No pictures since my basement is dark and my bench is a mess, but it is made using a metal work bench frame that I think I got from Menards with a section of counter top mounted to the top and pegboard behind for hanging tools. I also put a rubber mat, about 3/16 of an inch thick on top of the bench to protect the bench and parts if they are dropped.
As far as the size, the top is 72 inches wide by 24 inches deep and stands 34 inches from the ground. It seems to be a good height for me to work on standing, but I also have taller stools if I want to sit. The top has plenty of space for different reloading processes, or complete tear down or rebuild of a rifle.
If I was going to build my bench again, I would probably build a wood frame with wooden top and install the track system that Ken and Ben Schumacher use to make removal of my press easier.
