MyFax vs Powernet Global

I own a small business and only need to occasionally send faxes.  I didn't want to have to pay the phone company for a dedicated ring or line for a fax in our office even though fax machines themselves have come down in pricing to something extremely affordable!  I found MyFax to be convenient and well priced.  I initially signed up for the lowest plan of $10/month but realized that I wasn't sending or receiving faxes each and every month.  I called MyFax and asked them if there was any other plan that would suit my needs.  They offered me a $5 plan with up to 50 pages a month.  I was really impressed with the way they were willing to work with me instead of losing me as a customer.  I think MyFax is a great service- I really like how easy it is to create any file from PDF to jpg and send it anywhere.  It is so simple having my own fax number and receiving faxes and confirmations directly into my email account without having to log into MyFax to check and see if I have any pending faxes.  I highly recommend this company especially for individuals without a fax machine or small company's that do not use faxes on a regular basis.
