NDS flash cards confussion

Hello everyone, I have just signed up on this forum because i was in need of a little assistance. I’m in the market for a NDS flashcard that will enable me to run nds and GBA ROMs on my console.
However, I have been overwhelmed with choices on different solutions. I guess my question is, which is THE best option to go for which has the most features and abilities. Price is no real issue so all suggestions are welcome.

I have been looking at the ninjapass x9 and have done a little research on it. I have also looked at a few other devices such as the DS-Xtreme and the Neo-Max 8Gb combo pack. Yet I’m still rather baffled as to which device I should purchase. Thanks for any suggestions :thumbup:

Regards, Dan.
