Lived with the 120V charger in a 2017 for the 1st 6 months I had it. That got tiresome as the summer dragged on and the a/c usage required more and more charging. Since I bought the car used, I was not eligible for most of the rebates, but I did find a federal one that was available (iirc it was something like 25% up to $1K). I found a PowerCharge very basic EVSE (no frills other than a DIP switch inside to choose between 16, 24, and 32A; I use 32) on Amazon for about $400, UL listed. It just works. But it cost almost $3K to get the panel upgraded and a new 240V 40A circuit run across the garage (California pricing...with about $150 worth of permits). The federal tax credit covered 1/4 of the total, so it was near the limit. Added to the solar tax credit (installed some panels that year too), it was a very happy year for taxes, though we needed to hire a preparer to make sure all the paperwork was perfect.
The federal credit was supposedly expiring, but I understand it was extended (or else, it did expire and was renewed). And unlike some of the renewable energy credits, it can be be carried forward if you can't use it all in one year because of a low tax liability.
With an older Bolt like mine, there's no reason to pay for installing more than 40A. If you have a newer one, you might investigate getting 60, but while it's usually possible to fit another 40A circuit into a reasonably modern (last 30-40 years) suburban house panel and service capacity, 60 might be a little more questionable, especially if you're also considering going all-electric for everything else/replacing the gas heat and applianes, and adding solar probably with a battery.
