I bought ObjectDock Plus two years ago, and I just got an update. I think there is no time limit on ObjectDock Plus. It's going to be upgraded to version 2.0 soon, so they may change the update policy. I can't live without my docks; you can have shortcuts to everything instead of having to double-click on folders over and over again until you get to where you want. It will keep your desktop clean of icons as well. Just drag them onto a dock. Use tabbed docks to organize your shortcuts. Good luck.

It's version 1.90., build 535. The last update was October 24, 2008. I only got it recently through Impulse, which was unusable for me until I got high-speed internet (and don't laugh).
