There are a couple on ebay italy and ebay germany right now and whooo, first bid like 700 bucks, and they got it. Last week someone in Germany sold the portafilter separate from the machine and the total was around 600 euro! I agree with PC that is is on the cutting edge of collectibility, plus it has magic in the name. The pleated chrome body is totally "of the era" and is unmistakeable that it is vintage and way cool. There is no plastic and it is a very solid machine. but somehow I think that people think they are small club machines or something, like the early Gaggia levers or the Faema Urania. We like to think that it is the parts availability which is making the Faemina more desireable

and that may be a factor, but not a double the price factor. It's a market blip and a matter of who's looking and who wants it badly enough.
The Faemina really is a good machine though it tends to get a little hot, as do many, but when you wrap your hand around that hard rubber bumpy grip handle and hold for the first drips of preinfusion, then release the handle for a very nice espresso, well, it can make sense. The little pigtail of a steam wand is a bit on the short side to actually do anything with, but ours has a unique water fill valve on the top which we have yet to hook up, but with a length of rubber hose it would work fine.
I agree, some steep prices here, but maybe the Gaggia Gilda owners need to fill in a space in their collections.
