Ok, Assuming the first link on your post is the current one: good, this is the one I like the most. The other two got me completely lost.
I also want to say that it took me over 5 minutes to find out what the site was about. Moreover, on my (new

) 22" screen I have to scroll horizontally to view it all... and this happens with both ie and firefox.
Suggestions: make the main subject of the site clearer.
Perhaps you could remove one of the side bars?
I am voting for the top option of the poll
cheers!
