I have a website at: http://magicref.tripod.com
where I have reviewed many of the Bible Software packages available (sorry it is quite a bit out of date at the moment!). After having tried many of these, to include commercial programs like Logos & Quickverse, I like Swordseacher the best.
Granted, for some, Swordsearcher won't have the features and modules that they might desire in a Bible Program, but I have found it to be fast, easy to use, and equipped with most of the resources I need.
There are some good, free programs, such as e-Sword, OnlineBible, and The Sword Project, but I still prefer Swordsearcher.
