Alternative To Bondo?

I've used the NAPA body filler and had really good success with it. I'm amateur at best and learned a long time ago that I need to do as much metal work as possible and then use the filler to finish off an already "close" repair. I have also used their base coat/clear coat paints and primers and have been very pleased with the results. I live in a small town and NAPA is just handy.
