I would, honestly go with a 3DS XL. Black friday should bring price down since you are going to wait anyways. Considering target dropped price down considerably already in a sale earlier this year it can easily be said it will happen again, and possibly lower.
Why the XL?
Firstly, the 2DS is not just a 3D'less 3DS. It feels much cheaper, it only has mono sound, and its screen throws you back to the tiny tiny 3DS OG screen. I bought one for my little sibling since they wanted a portable console and its something I wouldnt feel bad over him breaking versus a precious XL.
The folding design is not bad at all, it protects all the important parts, for what, the sake of the bezel? Ive had my XL in a custom painted clear case (the one you get for $2 online) and Ive dropped my XL alot at conventions, trust me I freak out over my case breaking (considering its custom painted by someone on etsy from the UK) then my xl breaking.
If the bezel did end up cracking, its $30 and a screw driver away from repairing.
SCREEN SIZE SCREEN SIZE!
Try the vita, try the XL. then ty the OG 3DS or 2DS you will be disgusted by the OG 3DS/2DS. The tiny butt screen isnt worth the trouble.
Get XL, enjoy the epic large screen, and all the bells and whistles to keep you happy. because even with its tinybutt screen 2DS takes up more room.
Cant shove that sucker in butt pocket, noway. 3DS/XL you can even though it feels like your lugging a tiny brick but.....yea.... I rather spend $30~50 more then spending $200 later because I squinted so much while gaming.
ALSO in the XL if you have bigger hands they wont cramp up as easy if you ever played DS Lite, DSi, etc and had that issue. I experienced it alittle on the 2DS and I have tiny hands.
As for 3D, its a nice option to have. I have it off 98% of time, I used it in Fire Emblem alot. and I use it in Pokemon when I want to see my fights look more epic but I keep it off all the time otherwise. Sometimes though keeping the 3D on lowest settings gives the game a slight "pop out" which isnt like WHOA OMG QQ 3D DIZZYNESS but gives it a nicer overall look. but...battery...goes off~o. Playtime before prettyness.
