Italy Shore Excursions

I just found a link to an Italy site I used when we went before. It also has private tours and shore excursions here:

It gives an idea of what type of excursions other people might offer and the cost (between 150-250 Euros per person, sounds expensive, but probably in line with the cruise excursions).
