Thanks. It seems that every country but Italy appreciate Serenity.
Obviously I would have preferred testing/renting some time the board before thinking to buy it. And honestly an used cheaper model would be better for me; even if I've seen that the sportech model has a good price in Slovenia, better than in Italy.
Some time ago I've seen the Podersdorf centre selling on ebay.de/.at an used 2009 model for less than 600 euros (final auction price), I had the temptation to buy it but shipping cost to Venice mainland was huge (+130 euro). And in any case I surely want to test it before buying it.
