I have used Maxemail with no problems. This one is only available with a Chicago number, but would appear to be the cheapest & most reliable out there. $24 per year and easy to use worldwide to send, additional fees per page for international. https://www.maxemail.com/max/lite.html Even if you are outside of the US, if you think about it, does it really matter if you have a US number? How many times a year are you really going to receive a fax?

Good luck.
