The r4i I showed you doesn't need to get patched very often due to N stopped blocking carts. However, don't update your 3DS until there's a go sign from the r4 team. It currently supports the latest 3ds fw which is 9.6I see - thanks ArnoDorian. So the only real difference between the two is that the r4ids.cn one needs to be patched every now and then? That doesn't seem like a lot of trouble, if it's much cheaper than that DSTWO card, which is out of production.
