Die Hard it is! Like the old saying goes,if it aint broke,don`t fix it. The Die Hard I have presently did give me great service (and it`s only a 400 cranking amp) so I`m going with a Die Hard Gold (700 cranking amps). It`s $99. Most of the others at all the auto parts stores were in the $80-$100 range with the same cranking apms,so I`m gonna go with the tried and true.
