If you don't already, I recommend roasting your own beans. I never got good consistent results from store bought beans, but now I roast (which is surprisingly easy) I can achieve great results. Store coffee beans are usually way over-roasted for my taste.

But... There is an entire world of "third wave" specialty roasters selling quality light roasts...

i roast my own coffee and besides the roaster cost (which isn't negligible, but can be considered a hobby expense instead of a consumable expense, so not 1-1), it is 50-75% cheaper to roast your own coffee.

i order green coffee from sweetmarias.com and it's $5-8/lb which makes a good deal more than what's in the $15-25+ 10oz bags from 3rd wave roasters.

plus i learn a new skill and can roast to my preference every time!

Or find a local coffee shop that roasts their own. I used to buy from various sources and the roasts were all over the place. Thus, I was changing my grinder settings fairly dramatically with each new bag.

Having switched to a local shop's medium roast, I very rarely have to adjust my grinder after buying a new batch of beans.
