Whichever one you like better. Clearly I am biased, but not without experience with the IDMAX. I still choose the Magnum over it, some will differ. It's subjective.
Just makin sure... I found someone local sellin one for $230 (just got re-coned) with a box... (IDMAX that is) I will prob go with the IDMAX based on that reason alone (that it is local and cheap)
