In what universe. Metal roofs where I live are about 3 times what a 30 year dimensional shingle will run you.

I guess it depends where you live, and if you do the work yourself....
I did mine myself 3 years ago, took about a day to cover 1,800 sq/ft, and cost me about $68/square, compared to $78/square for shingles. This price includes nails, felt paper, flashing, etc....
FWIW, I paid $30/square 18 years ago for the shingles I replaced with the metal roof....
