Depends on how much effort you want to put in. I would never want a Senseo as they just seem a fancy way of making an instant. I LOVE my Gaggia Classic and it is part of my weekend routine to have a few well made coffees using freshly ground (using a burr grinder) beans and lots of frothy milk.
In fact it was my birthday at the weekend and all my presents revolved around either alcohol (a bottle of wine) or coffee (lots of beans, tokens to spend in my local coffee appliance shop) 🙂
Ohh, and I recently tried the Tesco own brand coffee beans – surprisingly good and a third of the price of the renowned Illy beans. Certainly represent very good value for money IMO.
But of course that might seem a faff to you so perhaps a Senseo would be more your thing (I hate the taste from them though – never been impressed when drinking them at friends' houses).
