Should I buy a Nintendo switch 2 or Lite?

Hi. Recently Nintendo released on Switch a game that I've dreamed about since I was a child, so I would really love to buy a switch so that I could play that game and many others. But I have a strict budget. Some suggested me the Lite one which is much cheaper especially if it's second hand, I searched about it and it says the difference is that it's smaller and can't be connected to tv. So I thought it was perfect as I don't really use the tv, I also read that I could buy separated joy stick to multiplayer but I really didn't understood that well so I'm not sure about that.

On the other hand, I'm afraid that in the future it could become obsoleted and stop releasing updates. I know that the switch 2 has really great characteristics and it's really worth it. But I don't know if the prices are ever going to lower do I can afford it. However if the Nintendo switch lite is not worth buying I will just endure it and buy the switch 2 in a year or more.

I even thought of selling my ps4 but I'm kinda attached to it and doesn't sell for much so....
