I am not sure about the code "2A" but it sounds as if your friend has a La Pavoni "europiccola" or "professional" manual lever machine.
My company sells both the current derivative of the above and the silvia, so I hope any comments I make in comparing one to the other are not looked upon as sounding unprofessional or as a personal slight on anyones choice of personal coffee machine but....
If you have had your heart set on a silvia and the question you are asking is, how does the la pavoni compare to the silvia, I am sorry but there is no comparison, and it would not be a "reasonable compromise" as the two models are worlds apart in the coffee they each produce.
In terms of straight comparison,
New RRP of La Pavoni manual lever machine in Chrome off the top of the head around $1300.00 ( not at work & cant check);
New RRP of for Silvia recently went to $770.00;
La Pavoni does not make espresso like commercial style, while
La Pavoni looks fantastic, while
Silvia is a box;
La Pavoni can only be used to entertain very small groups of people ( eg if you have a dinner party) because it has a small finite capacity in the boiler with no water reservoir, while
Silvia can be used to entertain and has infinitely larger capacity.
Many people swear by their La Pavoni manual lever machine, while
many swear by their Silvia.
The La Pavoni has changed very little in the last 7 years, and your friends machine if in good nik, will be very representative of the current model.
The right price, is whatever your friend is prepared to accept for a *machine that she does not use and simply takes up space at her place.
It is quite solid, and very simple.
I am afraid then, that you have to make the choice according to your own individual requirements.
Hope this has been of some help,
