Free (or at least way cheaper) DEVONThink alternative?

I rather like the idea of having a program to manage all my digital crap, since I suck at doing it myself. DEVONThink looks nice, but I just don't have that kind of money. I've been using Journler 2.0, but it's a bit clunky, particularly in how it does entries with tables. Yeek.

Any recomendations?
