Recommend good coffee blend?

i never drank coffee till recently, and don't know what are the best blends to get. when i was in hawaii this summer, i had 100%kona coffee- it was the smoothest stuff ever. but here on the mainland, you can't buy coffee with more than 10% kona. what are some other good blends? somalian? columbian? i see all these at the store but don't know if they're any good.
