I've been very satisfied with the steel I've purchased from seller kylharn on EB. The quality is great (they come raw/unpainted but who cares) and the guy ships almost instantly. He's having a "buy two of anything and get 10% off" deal (you can buy one expensive plate and the second can be the cheapest he sells). Plus, EB has a $25 off $119 coupon code today, PRIMO119. If you buy $119 worth, that amounts to around 31% off the prices you see listed.
