Open Source Alternative for Quicken?

I went back to the software aisle in Wal Mart yesterday to look for Quicken for my business stuff. I kind of choked when I saw the $80 price tag on it and started to rethink the logic of that. I am thinking I might be better off to pick up a Open Source alternative to that instead of trying to justify the cost of Quicken for home and business.

There has to be an open source alternative, so I am going to go digging and see what I can find that will work for it. I just have to get the time to get over to OSAlt and look one up, then learn how to use the thing. I had got something a while back, Gnu Cash I think it was called, that if I can find it on the computer I will see about using, but I think I had uninstalled it a while back.
