Hi all,
if you learn to make your own armour, it is a lot more cost effective. You need a way to cut steel, form it, polish it, and rivet it. You can do this with a saber saw fitted with metal cutting blades, an old stump or a lead filled leather bag to do your dishing with, some hammers, a shotput welded to a piece of square stock for planishing, some form of 'anvil', and a drill. Those are the basic tools anyway. Chainmail is even easier. I would reccomend learning to do riveted chainmail because butted chain doesn't hold up. It quickly starts to look like the dreaded mail moths have had at it. A great beginners article can be found here for plate.

just my 2 cents worth.
