You raise an interesting question, claraflo.
I have seen and felt both machines, but did not pull a shot on either.
The Elektra Micro Casa Leva is a visually impressive machine, and in brass/chrome is quite stunning.
The La Pavoni does not have the visual look at me of the Elektra, but its a great looking machine. Consider this, I looked* at the La Pavoni along side the Elektra, an Izzo Alex, a Giotto and a few other top quality machines, and the La Pavoni was only outdone by the Elektra. The La Pavoni is not a shrinking violet and will draw the eye (and the jealous glance) of most, but the Elektra is something else.
Performance wise, I would expect that the Electra may have an edge over the La Pavoni, but some of these edges are pretty narrow. In saying that, the lever crowd tend to believe that a spring lever is the way to go.
The AUD is high, its the end of summer, and there are more than a handful of sponsors who may be willing to sell you either machine, even if they dont generally keep the machines in stock. The 1k difference may be less than you think (or maybe more !!), but chat to a few sponsors and see how much you can twist their arms.
My Elektra Micro Casa Semiautomatica is a wonderful piece of engineering, form, design and function. I have been told that buying an Elektra is a decission to consider carefully, as you may become hooked.* :P
