source for iron angle brackets?

[Jim Franklin <jamesf@groupwbench.org>]

I want to strengthen a wooden stepstool by using right angle brackets  
between the feet and the step. I'd like something wrought iron like,  
with some scrollwork or other decorative stuff. Something like:

but maybe 2"-3" per side and not for $100 each :-)  Cast pig iron  
would do just fine, and I can spray it black.

The box stores had nothing and my google-fu is skirting the issue. Is  
there an online place for these?

thanks,
jim
