I picked up the cheapest Die Hard from Sears two years ago just to be able to get my 69 out of the barn where it had been left to rot for 15 years. When I started the car for the first time (three weeks ago) the battery still had enough juice to fire the car. I also use Ricks cheap cables #SRP-53 @ $9.95 (+) and the #SRN-32 @ $6.95 (-) and the fit well, look good and do the job.
