(Do you bring the frothing pitcher as well like I do?)
Oh, and a Pentax Optio, similar to Bek's but older, has been great for me. The biggest thing is there is no shutter delay. I keep it in an Altoids tin.
I have one of these (2 shot Bialetti Mini Express):
I lightened it quite alot by removing the plastic handle, removing one of the copper pipes and plugging it with a screw which I then ground the head off of, and then I cut/ground off the second 'shelf', and went crazy doing a 'drillium' treatment on the remaining 'shelf.' It looks insane now and produces one respectably sized cup of coffee. I always have my coffee black so I don't need a frother or anything like that. Sometimes I add hot water to make an americano though.
I pop it on my MSR pocket Rocket for a little while on low, but maybe a trangia would be a better option...
