Best place to buy gateway 3ds in the US

APPLE VALLEY, Calif. - April 9, 2014 - PRLog -- Recently, I just thought about getting a new 3ds xl for my son as a birthday gift, and since using a flashcard with his old dsi I would like to purchase another one and right now its between the mt card and gateway 3ds I did some digging around online and some people we saying that the gateway 3ds card can play 3ds roms, and it's the first working 3ds flashcart out there.
From what I've gathered, it now has 100% 3ds game compatibility, in other words, you will be able to play all 3ds backups, yeah, that's about 300+ 3ds games, including pokemon x , pokemon y and animal crossing, that's my son's favorite game. MT card's greatest advantage is multi-rom support, and gateway 2.1 omega firmware just updated that, and allows users to play multi-rom games.
It is generally considered as the best working 3ds flashcart out there, and the team behind the card is constantly updating the firmware on gateway 3ds flashcart. http://www.r4flashcart.com/13-gateway-3ds-flashcart-play-3ds-games-on-3ds-xl-3ds.html that's where i bought the gateway 3ds flash card, shipping was free and quick, the resellers in the US (that are actually legit and located in the US) are very very few now, and r4flashcart is the best place if you are in the US, btw, shipping is free to everywhere i belive.
