Mary Ann, I'm not sure that my attempt at brevity got my point across.
It's definitely worth seeing if your broiler is strong enough, but the odds are stacked against you for Neapolitan in a home oven. A WFO is an incredibly worthy goal, but, between now and when you build one, there's nothing wrong with a temporary stopgap- and, there's no better stopgap than a Blackstone. $379 guarantees you Neapolitan bake times- something that no other equipment in this price range can do.
I haven't started playing with my BS yet, but I've seen what it can do. If you want Neapolitan pizza, but aren't ready to invest in a WFO, there's no better route to take than a BS.
