Maybe the cheap one is the no OS version? It's not at all clear from the Amazon listings. For a NINA setup you want the one that comes with Windows 11 Pro. It's more clear on their website - that's where I got mine. The price there is in USD.

Edit- The cheaper one does say 'Linux' so I read that as no Windows OS included.
