Buying a used New 3DS XL is a PITA

So after i tried Citra emulator, i realized that to experience 3DS as its originally intended, i need the original hardware due to its 3D screen. Sure on PC it looks much better and runs smoother, but the lack of 3D doesn't sits well with me.

Thus i revived my old original 3DS by replacing its SD card slot that was broken. then... UGH THE SCREEN IS SO TINY. Now I'm hunting for a used New 3DS XL, but it is a PITA:

rant time:

1. Its unclear what screen they have (IPS/TN), and most seller doesn't even understand what the heck that's even means.
2. the used market was flooded with cheap used N3DSXL from japan with custom firmware already preinstalled. But i want to transfer my legit games from my normal 3DS to N3DSXL
3. I cant buy one without sd card (i already have one on my original normal 3DS), instead, thesellers keeps telling me that i can request any games i want...
