Graphics program with a clone tool

[Sundance2007]

I am looking for a inexpensive graphics program that in it's tools has a clone tool. I want to be able to retouch dust spots and such on my photos. I know there are programs out there like Photoshop and others that have this but I would like to find something that is free or low cost.

Thanks,

Steve
