Carpenter is one of the big guys, but steel suppliers are a major PITA
to deal with. A few years ago it was a $500 minimum, probably more
now. Maybe you can sweet-talk them into giving you some samples.

Many years ago some outfit in the UK had transformer "kits" with the
primary pre-wound, you just have to add the secondary. Don't know if
they're still available. I bought a few from Maplin.
