I've been demonstrating Accordance and BibleWorks 7 and reviewing Bible software in class recently. We did a group order for both -- first time I've ordered Accordance -- with a group discount and without a hitch.
While there are up to date websites: Bible software Review, there seems to be more on the web not covered by every site.

In the public domain there are limited English translations. The NRSV translation (approved for lectionary use in the Episcopal Church) has proprietary costs.

Some sites we examined use Bullinger (d.1913) for Greek Word Study, Short Definitions. His lexicon was published in 1877. Longer definitions of Greek Words might be from Thayer whose lexicon was published in 1899. These tools are completely out of date now since they take no papyri discoveries or modern linguistic tools (e.g. semantic domains) into account.

Standard Greek and Hebrew coding is CATSS, Computer Assisted Tools for Septuagint/Scriptural Study.
