I've had my mobile office setup for the last few years and now I'm looking to ditch my landlines and go 100% mobile, but I still want to offer my clients the option of faxing their orders.  I've been on Google checking out some of the various e-fax services out there and wondering if any of the SOT faithful have any opinions or advice about which one is the best.

Thanks in advance.

Regards,
Scott Perry
