What would you guys recommend for a newbie to the DS scene? I've read up and I personally like the EZ4 more, but I've heard quite a bit of compatibility issues with them, except with an EZPass3. I also looked at the SCSDMini with the Superkey, and they seem to be a good product. But then again, lots of people are on the M3 bandwagon. So many choices, I just can't pick!
