I have an R4, and have been pretty happy with it, but I have the itch to upgrade a little. I am on a budget, so I don't need the most expensive thing going, just some suggestions on a good balance between price and features. I want something with good support from the producer, good availability, Really good compatibility, and is compatible with the 3-in-1, since I like it and don't need much more for GBA. Start the wars over which is the best. BTW, I would really like to spend $60 US or less if possible, and use my current micro SD 2GB card, at least for now.
