Is the hp 97 not the big brother of the hp 67? Shouldn't it be faster?

edit: added the 880P (now it has 2 results)

plus, yes Italy is nice (its landscapes) as mostly every place in the world. I mean even the tundra in Russia is peculiar in some way.
Still I don't like the average mindset there, at least from the regions under Florence/Rome. In the North they were/are a little bit more organized (nonetheless there are some groups in the North that, well, are a bit backwards. Like people following separatists parties in the North-East or populists).
