I use a Cabelas digital scale. It gives a read out in one ounce increments.

Plus:
Cheap: only about 15 bucks
Easy to use
Will store in memory the weights of fish caught
Weighs fish in once ounce increments up to 50 pounds.

Cons:
Not certified by any tournament organization that I'm aware of.
If you leave it in the sun with the screen side up it mades the LCD screen go crazy - it does recover from this though if you put it in the shade for a while.
It has a big hook thing to hold the fish. For smaller sunfish this can be somewhat of a pain. You end up having to grab onto the fish to put in on this big hook.

Overall for fifteen bucks I can't complain. I have no idea how accurate it is though. Probably accurate enough, I've just never tested it.
