The best RAM will be identical to the one that's already in there, just with a higher rating. If it has a 2GB stick in there now, buy another one from the same manufacturer with the same specification to put in the other slot.

If both slots are already in use - say, two 1GB sticks, buy two 2GB but again, the same as above.
