Is there a DS devkit that allows debug not only on assembly code but also on C? I basically mean someting that would allow people to produce a professional product. All this 'send across WiFi' all sounds great, but you get no debut at all!

ArmDevKit seems the right software, but what is the right hardware? Has anyone tried the no$DS dev-tool? Is it worth the rather steep $1500 price tag. I only have £1500 for all tools for Wii & DS (including PC!).

Thanks,
