How 'bout an inexpensive current xformer, which seems to be what the OP
wants?

I need a *digital* interface which can be read / monitored by a computer.

The Coleparmer module does the trick, but it just goes to max 25A and I
hoped such modules would be less expensive than those...

Other comments?
