Ok, here's low down.
I tested their prices with just a normal ansi, 60% layout and it's not as cheap as I thought I remembered it was.
1.5mm SS plates would be like $42 before shipping for a quantity of 10-49 and about $38 for a quantity of 50 or more.
Also for those of you asking for brass, I didn't see anywhere that BBS offers a brass material.
There is also lasergist who might be able to give a better price on quantity items like this, but we would have to contact them. If we do explore this route, I think it would be best to approach them with a final version of the plate we are going to use.
Sorry for the false hype, I thought I remembered their prices differently
