Are there any decent, cheap (less than $40-$50 -- or better yet free

) editing programs available? I downloaded the PSP download a while back, but the demo expired before I really could learn much and I couldn't reinstall it.

I'm not looking for something with all the bells and whistles, just something to do the basic editing stuff (cropping, resizing, adding some text, etc). Figured this was the best place to ask.
