Damn!! Fulvio you write like an Italian!
-Unfortunately you are right! I feel the same way, but there is nothing you can do about it. As they say in the US, love it or leave it!
Beside the licence, I've paid about 3 times more on custom works. But it's ok nothing isn't even comparable to flynax flexibility, surely 80$ here and 150 there and 220 there etc, etc, makes your site expensive but unique.
Interesting point is the multilingual system as you say, like the mass mailer, multilingual site with only one language to choose for mailing? but if you pay 80 buck they'll make it for you in few days.
There are a lots of thinks that they need to fix, but to me they don't even care, they are so unique with no competitors.
Understandable if you build the site for a client that you have to keep asking more money makes you look bad.
By the way you have a PM, please check it out.
Ciao.
