Howdy,
If I were looking to upgrade from a Rossi, I would buy a yellowboy, a 66 clone. Here's why:
It's at least $100 cheaper than a 73.
It's different and good looking.
It works as well as a 73, for most folks.
Great resale value.
It provides a taste of the toggle link action.
I bought a 66 early on, an antique finish 45LC gun. It shoots very well and I sure like it. Hope this helps,
