The problem from my perspective, running a small DJI fleet in Civil Engineering, is that there are few comparative turnkey options from non-disapproved drone brands that actually compete with what I'm using now. The ones that could, are drastically more expensive.

From my understanding / research, the approved suppliers are largely focusing on the LE, Military markets.
