Blueberry Software distributes a neat demo of their file-conversion filter.

Send them a blank tape, they send you a tape with their complete filter product  
and the full manual. The demo filter does everything the full version does -  
except that the converted text is full of spelling errors due to an encryption  
algorithm.

You can fully examine the product and evaluate its output for as long as you  
want. When you send Blueberry the purchase price, they send you a password -  
install the password to disable the encryption, and you are ready to go.
