Thanks for the reco @abmr2d2 - yes, I have used Azom in the past - but it was from 2016 - at the time, it was a beast of a machine and it gave me literally zero problems for 6 years other than a slightly loose N key. At the time, the company was small and I spoke directly to the founders/really knowledgable sales people. Not sure how they are now.
I'd say definitely keep it specific machines for specific purposes - stay away from ROG SCARs etc and 'thinner' 18 inchers. Go for thicc machines - better heat dissipation and longer lives. Keep a tablet or something like a 11-13 inch Windows machine for on the go.
