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?

Terceiro- can you give us...

Terceiro- can you give us some examples as to how DEVONthink really helped? I'm intrigued by these types of programs, but the amount of data entry places things in the rough to use category- i.e., only until you feed DEVONthink tons of stuff, does it really become a huge tool... the more you feed it, the more it gives out me thinks...

So, when did things start to click for you with DEVONthink, and how did it click?
