if you're bored with Switch, they're selling online for decent money since they're pretty much impossible to get new thanks to the supply chain disruption. Especially if your Switch in unpatched, which you can check here:

Of course if your Switch is unpatched you can put custom firmware on it and play all games for free, though you can never go online with it again in that case.
If you're looking at a new console the PS4 is the way to go. It's absolutely loaded with great games in all kinds of genres and most of the big blockbusters that aren't new are $20 by now. The exceptions are Sekiro which still only goes on sale around $40 and Red Dead Redemption 2 who sale price is usually around $30. IMO PS4 is the no-brainer best console to come out since the PS2 twenty years ago. And it's also the cheapest console I ever bought (in inflation adjusted dollars) with the cheapest games.
