If you're willing to import, tuxedo computers is another great choice. I can personally vouch for framework but I'd caution if you're looking for the 16, it'll be a bit before they're available. 13ish batches pre-ordered, with batch one shipping in a few weeks, it may take quite a bit to get. The 13 though is in stock and shouldn't take too long to recieve
Edit: oh sorry, 13 inch is your preference. I'd strongly vouch for framework. I'd also say stay away from purism due to their scummy history on the phone if you care about that.
