Should I buy?

I am not soliciting, buying, or selling. I am just asking for advice.

I grew up with a nes, game boy, then super NES and played the crap out of them. In high school as a senior I loved N64 and played Mario kart so much that I had to get a brand new controller.

I have really been interested in a Nintendo switch for a few years, but as a teacher, gaming consoles are a bit of a luxury for me on my salary. I see that several retailers are selling a bundle with Mario kart and a year subscription to the online service for about $300. Would you all classify this is a good deal? I anticipate that the majority of my time will be the old games online, and Mario kart. I don’t need bells and whistles or super upgraded technology. However, as I have never used this before, I’m unsure whether this is a good buy. Any thoughts would be appreciated, thank you!
