I was looking for a charger to take with me when I dry camp/boondock without electricity. I have a cheaper model I picked up at a Sam's Club which at least used a computer to control charge. But I wanted something a bit more sophisticated.
I bought a Xantrex X-power Jumpcharger:

Although I am not happy with its condition upon arrival from Amazon.com, I do like the value for the money. I paid about $75.
When you connect a semi-dead battery to the unit, it will allow you to pick the initial charge rate. It will then actively step the rate down (through the three types of charging) until its full.
