Everything of the above is not an option for me.

But at least when buying on OZON I can return it within 7 days without any questions.

I'm still thinking that for the sake of curiosity Quest 2 is the best option for now. It's not a top-notch option, but it's decent and it's relatively cheap.

I'm not even sure for example if I'd be diligent enough to learn what's needed in DCS. So I'm not even sure if I'd be using it for a long time or just give away to someone like you did with Quest 1.
