Coffee Makers

We have a great coffee maker in the house, it’s a Gaggia  'beans to coffee' and makes perfect lattes and expresso’s at the touch of a button, however, its big, heavy and expensive so can anybody recommend one of the smaller cartridge type coffee machines for the van….. we are looking at the Nescafe Dolco Gusto range at the moment, anybody have one ?…..there must be others too worth looking at.....
