I am really green behing the ears on this stuff, but my younger boy now wants a tank just like his older brother's. Why the big price difference? I understand the metal gear and tracks but will it actually last longer? From the pics they look like The typical Heng Long pot metal gears and not the steel gear set? AFter our problems with my older boy's tiger1's stripped pot metal gears, I bit the bullet and bought the 260 dollar toy for Christmas. Is it worth it and why? Please tell, I have thick skin.
