Not sure if it's been mentioned elsewhere in EF but I came across a caps system at the Comptoir in Lausanne this past Fall from Trottet (I believe based out of Geneva)...They had a little stand and a deal that was practically free for a machine and a good number of caps
We had tried the roasted beans from Trottet in our Delonghi automatic machine and had enjoyed the flavor...Had talked about getting a 2nd caps system in the event we needed to service our Delonghi
There are only a few machines from Trottet and they are of the cheapest quality, IMHO, but we've been very impressed with the quality of the espresso it puts out...Caps are biodegradable which makes it a plus over NEspresso...The caps are quite cheap too, comparatively (20 CHF for 50 caps)...but most importantly it's consistently high quality espresso
They also have the online ordering system etc. similar to Monodor or NEspresso
Something to consider I guess
