If you have a kid in school, you can get an educational license for Lightroom, I think it's somewhere around $99 versus the $299 full price. I think the regular version was on sale for $199 at some point in early December, too. That's will go a lot of things but won't do stuff like put someone's head on another's body or make collages or that type of thing.
Photoshop Elements and Paint Shop Pro are worth consideration if you're after more "editing" and less "processing and organization" which is what LR specializes in.
