Ad you don't need to be rich to get one of these " Freccione ", or the even more affordable GMT 1675.
You can have fun for much less than one year ago.
Don't go for the details or the particularities, but only for your pleasure, a nice patina and a good condition.
If you want to go further on the details, yes, you're right, you will have to buy a book, and to do big homework before.
But it is not necessary...
Best,
Nicolas
