Yeah B&H is a great shout for pre-orders since they're usually pretty honest about dates - honestly though id probably keep an eye on the DJI Store directly because they usually prioritize their own stock first and it's basically the safest way to ensure you're getting a legit unit with a full warranty. I'm always a bit wary of random marketplace sellers on Amazon because sometimes you end up with a grey market model and then DJI support wont even touch it if something goes wrong - which is a nightmare if you're dropping several hundred bucks on a DJI Osmo 360. I think Adorama might have some coming in soon too - they're super reliable and usually have better customer service than the massive retailers if something is DOA or has issues right out of the box. TL;DR: Stick to official retailers like Best Buy or Adorama for better reliability and warranty safety, avoid third-party resellers if you can help it!
