I've looked at CodeLocker (poorly styled and relatively unflexible, but free) and Source Code Library (Overzone software - very nicely styled, looks flexible, but very expensive - $80).
Ideally, I'm looking for a relatively simple, inexpensive program (not an online website) that I can save text data (source code) with a title and keywords, maybe even a description. It would also have some type of search functionality.
