I'd recommend getting a prusa kit for anyone interested in building stuff. The instructions are easy to follow and broken up nicely. IMO it's also fun to see the parts and a glimpse of the design you wouldn't see buying a complete printer.

IF I managed to scale what I'm doing then this is my plan. I've built a RepRap in the past so I do understand the inner workings, however if I scale up I'll by going with Prusa, so building the kit means that I'll be able to actually service them myself (and if that happens I'll be adding 2-3 a month to my farm).

Bambu are cheaper in Cap Ex but based on reliability they will likely have a similar TCO after a year. Also as a Chinese brand Bambu are risky. If we get tariffs or some kind of international situation then things could be problematic.
