Hey, I've been wanting either the Supercard DS One, R4, or M3 Simply. I do not know which is the best and works well. I am hoping that you guys can give me some advice in which to get. I really want the best working one. I have one more question, is it true that the NEWEST Supercard DS One contains a lot of bugs and errors? I've been reading a lot of negative reviews on sites about that.
