Personally i would abandon the idea. I had the chance of trying all the newfangled coffee pod machines. Every year there is a new one on the market, just as bad as the previous one. after a while the machines are obsolete, and the pods are discounted to nothing until they are out of fashion. 2 weeks ago, senseo pods were on sale at 35 pence for a bagful... the coffee is absolutely minging, acid.
i still go back to my 25 quid carlton espresso and filter coffee maker. I buy the lavazza beans from tesco at 8.99 a kilo, grind them, and voila'...... nice and yummi espresso. better than you can find in stabucks, nero, primo or whatever chain you care to mention.
