hey my acekard broke, and i wanted to try this r4i is it worth it? http://www.r4idsn.com http://lightake.com/detail.do/sku.R4_3D_Upgrade_Revolution_for_3DS_DS_DSL_DSi_DSi_XL_LL-36808
supercard dstwo is by far the best card cards from r4idsn.com and r4ids.cn as well as the dstwo all support dsi 1.4.4
If i was you, i would purchase from http://www.zhuzhuchina.com/store/dsi_r4i_gold_slot-1_flashcard_type_d__www_r4ids_cn__3ds_1_4_3_compatible_wood_3ds.html but if you're from the UK i would recommend a UK supplier
