im based in the us and looking for the best place to buy an acekard2i pre updated to work on the newest 3ds firmware as i dont have access to another ds or 3ds to update the acekard any help would be appreciated
recommend this site, http://www.dsflashcart.com/acekard-2i-flashcart-for-nintendo-ds-dsi-3ds-p-251.html  us based, preupdated to support latest 3ds v4.1.8. bought 2 times from them before, everything is working great about them.
bought from this USA official agent : http://www.digitopz.com/acekard-2i-p-25.html ,.Preflashed firmware,works perfectly on my 4.1.0-8.A good shopping experience for me,maybe you can reference or you can google and can fine tons of stores.
Ak2i from oz3ds has been updated to support the latest 3DS v4.1.0-8 and DSi v1.44. it is listed on its official site as an Australia reseller:http://www.oz3ds.com/product.php?id_product=16 Received one with free shipping.
Here: http://www.dsflashcart.com/supercard-dstwo-best-flashcard-for-ds-dsi-3ds-p-252.html Preflashed and authentic dstwo, As long as the dstwo is authentic not the fake. It can play GBA games.
here you can find http://www.martgame.com/nds-accessories/r4-card.html Too many flashcard can play GBA games, like Slot-1 Flashcarts: Supercard DSTWO, EX4i, iPlayer, iSmart MM, CycloDSi Evolution (only works on a DSi and is extremely limited), Slot-2 Flashcarts:EZ Flash 3-in-1, EZ-Flash IV.
