I bought Don Alm's Fax Bux ($297) and FaxFinder software ($297) about two years ago.
FaxFinder did not work as advertised. The reason was that FaxFinder was based on 1994 technology and was totally ineffective for retrieving fax numbers with today's newer computers.
I complained to Mr. Alm. He gave me one lame excuse after another why it was my fault (Are you familiar with his personality?) and finally agreed to give me a refund for FaxFinder.
Guess what? Mr. Alm never refunded my money or answered my numerous emails requesting that he do so.
He may be a great saleman - but my experience with the man is that he over promises and then does not stand behind his products.
If you are looking for a solid business opportunity, I would suggest you look at Jim Straw. From what his customers say, the man is a God. I can assure you, Don Alm is not.
