Questions about Pietta 1851 Navy .44 cal

So I see this black powder revolver is a popular choice here in this subreddit. I am considering getting myself one because I want to get into black powder stuff and oldschool weaponry, and so I am wondering if the Pietta 1851 is a good "first black powder weapon" of choice for someone who is new to the general concept of black powder.

I am mainly asking for things like.. pros.. cons.. and things like "how cheap is the ammo in the U.S." and stuff like that!
