Over Christmas John Lewis was selling their own make ones for I think £10 a good cup sized one. So I bought 2 one for the boat and one for home. Nothing like waking up and smelling the coffee.
I know this is probably a dead thread now...bit I just stumbled across this fully manual, fully portable espresso machine... Handpresso I may have to invest in one... P. UPDATE: fixed the link.
It's very much alive& kicking in my brain as I've not purchased anything yet myself! Unfortunately your link doesn't work ?
