Both vBar and MagicButton are free. I have used one or the other at various times, preferring MagicButton up until the newest version of iLauncher being released.
WA2/WAD can be thought of as a front-end to the Today Screen front-end. It is quite elegant and powerful, with a learning curve to match. It also provides cascading menus and a "real close". I tried it several times, but it is just not my thing, I guess.
