Stop in for a cup of coffee

I am looking around for a battery jump pack any recomendations under $100?
The Viking brand from HarborFreight is really really good. Costs about 80-90 bucks. The one I have is 3 years old now and has been used a TON around the farm jumping tractors, semis, my Jeep. And the kids four wheelers. Mine came with a binder about the size of a book. I love it so much that when my in-laws asked what I wanted for Christmas this year, I asked for another couple of these so I can keep one in each vehicle.
