depends on the scale... But probably anywhere from 40-60% more expensive to buy than build. Me and a buddy are looking at building one, then scaling it. Most of these places are just getting a shop to preassemble them anyways and then reselling. We are looking at in house manufacturing in the states. We might be the only ones if we do and I know how to self host everything to sell them p2p in the states with no middleman. We may be the only ones doing that if we do. Buddy is finishing his lab now. This will be the first project built there.
