Actually "ANSI M57" is 175W, so if they're 250W ballasts they're probably "ANSI M58."

175W - M57
250W - M58
400W - M59
150W - M102
1000W - M48
150W (double ended) - M80
250W (double ended) - M81

The M80's and M81's seem to be a fair bit more in cost ... I remember when I looked into this I was looking at >$150 per ballast...
