+1FWIW, I found that a good grinder does more to improve the taste of coffee than a fancy coffee making machine, though I have one of those also.
I grind the cheapest bulk beans I can find at Costco. With good grinder and a descent drip pot, it may not be perfect, but it is more than good enough.
A good grinder made a big difference for me as well. A post by a fellow forum member (here ) led me to the beans that immediately became my standard. Every once in a while I try something new, but so far, no replacement in sight. Starbucks is everywhere, so getting beans is easy.
