I too went with Micron/Crucial even though it was a little (& and I mean miniscule) more expensive. Their quality reputation is backed up by everyone I know having no probs with their installation & running.
I too perfer Micron- they've got good service and they send the memory 2nd day free of charge! Not to mention that also sell DDR for the cheapest right now. I just bought 256 megs of PC2100 for $68!!!
