What is it, really? After looking for clues on the site, i found so few about it...
Apart from this post.
I may have the opportunity to get a hold on a 2-group Faema No Stop at a really good price, and i barely can find info on the web about it. It looks like it shares spare parts with the E64 group... Can we say it uses the E61 group, in an automatic way? If some of you might have some more, i'd be very pleased to know if it's as good as it looks like (i mean, mostly backside )!
I'm currently restoring a Rancilio L6, and may also be able to get a 2 lever Faema President within 2 months. Would this No Stop find its place nicely? Or should i run away from this machine?
Moreover, some say Faema's reputation ended after the E61 group... What is your opinion?
Thanks in advance for your answers, regards from France.

Good luck.

The the E64/66 and No-stop are thermosyphon groups with a dual piston preinfusion/exhaust setup similar to the E61, except that they used solenoids rather than manual leverls. Parts are not interchangeable with the E61, but may be with the E64/66. You can get parts and see the diagrams at coffeeparts.com, a great Aussie place that ships.

Many thanks for your answer, Jim.
Would you say it's pretty hard to restore versus other machines, as i've been told by a french board fellow member? Moreover, how should it compare into the cup to a Vibiemme Replica for instance?
I mean, are the technical aspects of the NoStop worth using when it comes to the cup, compared to the rather simplicity of the Vibiemme? Sorry if my questions look a bit odd...

Nothing odd about the question, but I don't know the answer.

My guess is that all the "descendant groups" of the E61 are pretty much as good as the rest. The real quality differences I've noticed comparing the Faema Legend or Kees Mistral to regular E61 boxes for homes is that these much more consistently good machines pay a lot of attention to the sizing of the thermosyphon and HX and to the positioning of the jets, so that flushing routines are unnecessary. The group is always at the right temeprature and can heat sink any deviation from the HX. The ultimate in this is the NS Aurelia, which is rock steady on temperature under all conditions, and is the best "walk up and make a shot" machine I've ever used. Both the Legend and the Mistral come close in (hopefully competent) user friendliness.

So if you are going for taste, your best bet is to "restore" the thermosyphon valves and jets on any old E61 box.

I've come across several cafes in the Northeast US that use the NoStop, and all the baristas seem to like it. It is a very solid, heavy-duty machine that takes a long time to warm up.

I finally found the Vibiemme would be better for our use, and easier to restore (though i'd be interested by the NoStop too... ). Many thanks for all your replies! (sorry for the blurry pic, i did not take it...)
