We have a Nespresso machine (can't remember the exact model), and we LOVE it! We just got it as a wedding gift, and the coffee is amazing! I was unsure about it at first for the same reason as you...I didn't want to have to buy the pods. But their coffee is so darn good that I honestly don't mind. And it's not that expensive. The pods are $.55 and .$62 each. When I compare that to the price I pay for a latte at Starbucks, it's peanuts! It's super easy to use too, which is a big plus. The benefit of the pods is that there's no mess, no cleaning, no coffee grounds to dispose of.
HTH!
