This advice is a bit more difficult with the current LPCAMM situation. In the US, besides Framework, I was only able to find a 32GB module from Adorama, seemingly a left over new stock Crucial module that I assume must be discontinued in Crucial-branded form, or eBay. But it is far cheaper than Framework’s price ($250) and seemingly still available.
(Interestingly, Adorama’s website says that it’s “trending.”)
You’ll save at least a little bit of pocket change buying your SSD elsewhere at the very least.
