be hard to get rid of my m8 (tell my m11 that, never used in 2yrs as the 'backup' radio)...but the mars is a great radio. so what if its not new. i still see them. must be for a reason, same reason as the m8.
dx2.0, comparing a 2.0 to a mars or m8 is sadly....laughable. both of those 'seasoned' radios will go laps around that setup.
