Where do you buy an Orange Pi? When I was researching these devices I found it to be extremely weird/sketchy. These are three different websites all apparently from different companies:
Welcome to Chinese fruit clone vendors. They're all copying RPi and now copying each other. Good luck spotting the good ones.
Then when you get the device it won't do anything new after a while because the vendor never maintains their distro and the GPU or device tree are is proprietary so nobody else can either. If you're lucky maybe there's an Armbian build which marries new userspace with the older kernel and its unmaintained drivers.
This is why Raspberry Pi still dominates this market.
Ebay or Aliexpress are good options with buyer's protection. I bought quite a few OrangePis in my time, although that was at a time when the Orange Pi Zero was 9 EUR a piece. At current prices, I don't see the point.
The OPis themselves were quite decent devices, Raspbian worked very well on them.
So the third link is the official one? Its footer has some very sketchy looking links, including to two different telegram channels, three aliexpress stores, and some guy's skype username...
Then again, we might not even be seeing the same site, since it forces http:// and could be modified in transit by anyone on the path of either of our ISPs and the web host.
In my experience on Aliexpress, 3 stores aren't unusual. Most of the stores I buy from on Aliexpress (mostly 3d printer parts) have at least 2 stores. Even the reputable ones like BigTreeTech which is a pretty popular for 3d printer control boards have at least five stores by my last count. According to them, Aliexpress don't allow multiple accounts to manage a store, so they make a new one for each salesperson.
Orange Pi / Xunlong is a stable brand that's been primarily on Aliexpress for 7-8 years IIRC, producing various boards, all of which work fine for me. Very reliable seller, and the product + it's cheap. In the past they had Orange Pi PC, which was half the price of Raspberry Pi 2 or whatnot and much better in connectivity (4x real USB host interfaces, ...).
Their software I would not touch, but I never had to. Most Allwinner and Rockchip boards are well supported upstream. I just upstreamed support for Orange Pi 5 Plus a week ago or so.
All you ever need with these random boards is to build your own Linux kernel and bootloader for them, which is a few fairly standard steps, and then you can use any normal aarch64 distro on them, even if the board is not "supported" by the distro.
I just have a script to cross-build the recent kernel for the boards I own, and update it remotely. Not a huge issue.
