David,
I use TrustFax. I'm not allowed to post their web address because I haven't posted 15 times to this site yet, but put a "www" in front and a ".com" behind it. They have several plans and you get a local fax number. You can get an 800 number also. They have a $9.95/month plan that is probably what you're looking for. I had to upgrade to a $18.95/month plan due to the quantity faxes I was sending and receiving. I've used them for about a year and it's been great. I print what I want and I receive faxes to my Blackberry via email. Just thought it may be what you're looking for. Good luck.
