I got those two for $20. One for me and one for my son. Working on setting up the custom firmware and Nintendont to servers since the closure of the official ones.
In my house alone I have two 2DSes, one 3DS, three 2DSXLs, one N3DS, and one N3DSXL.
I'm tempted to get a couple more but I've already modded the N3DSXL with a huge SD card and a ton of games. Personally I think the N3DS is more comfortable but I haven't wanted to transfer everything over to it.
It’s was pretty easy (failed once because I didn’t quite follow the steps, you really need to count your button presses and screen taps, any extra press and it’s a do over)
