Pretty nice list. But you missed to include Conjurers Encrypter which is easy to use and also has anti-brute force technology.

What about www.lokibit.com? There is the cryptographic encryptor that I use. ***P.S: I extracted from the Zip instead of the downloader.
*WARNING!!! Due to the low funding of the website, the downloaders will offer toolbars that were hard to erase AND WILL INSTALL TO YOUR COMPUTER WHEN YOU OPEN THE DOWNLOADERS. (I got rid of it from the virtual machine.)
You should only download the Zip Archive package. (+scan)
