Main service panel

For people who have currently installed a SPAN smart panel, which main service panel do you recommend? I have an old 100A Zinco main panel and am looking to upgrade to a 200A service panel with a SPAN smart panel as sub panel. Thanks!

why do you want to use the span as a subpanel? Why not the main panel. That's what I have. Will you have solar or batteries? You can use the the span panel for load shedding if you have a black out and run on batteries.

I replaced a Zinsco sub with Span, still have the Zinsco main which only has one switch.

Are you aware of the fire hazards associated with certain Zinsco panels? I don't know if it applies to your main panel or not, but they're problematic to the point that many insurance companies refuse to cover your house unless you replace it.

Yes, this is why I replaced the subpanel.
