Best free backup app?

[arizonaomnia]

So I want to clear up some space without moving to one of the cooked ROMs floating around (mostly because all of them leave something out that I want on the phone), so I'd like to do a hard reset and clear out whatever is taking up so much space (even though I'm installing to My Storage when I put in an app). I'm using the leaked ROM, and when the official one comes out, I'll probably upgrade to that one, and when someone cooks THAT one and perfects it, I'll probably upgrade to THAT one.

Problem is, with three kids and a wife who, oh, likes me to pay attention to her once in a while, I don't want to spend all of that time every time reinstalling everything and re-doing all of my settings and re-configuring all of my SPB widgets and whatnot. But....because of the aforementioned family, I also can't be shelling out more cash for backup apps. Is there a good backup app I can use so that after I hard reset (or upgrade firmware), I can restore the backup and end up with the same features and settings I had before (including Opera favorites) that is also free? Or is there an easier way?

I love this phone, btw....it's the only thing that's really putting a dent in my Palm Pre envy....
