D'oh. I was excited that I might actually be able to throw out my fax machine. I just sent a fax through HelloFax and the service seems to be very useable. I went through the interface trying to figure out how to add a credit card to my account and determine how expensive the service is. But they don't have pricing yet.

My small business uses Packetel for incoming fax-to-email and a real fax machine for outgoing faxes. I would love to get rid of the fax machine and the stupid copper phone line it requires.
