I have both the Sirius Pro and the Triton charger. I use the Sirius charger about 95% of the time because it's so easy and gives a reliable and quick charge. I only use the Triton now for odd batteries like the glo-starter or my RC car batteries. The Triton takes a while to get used to with all the different menus and options.
You can get the Sirius Pro at RadicalRC for $119.

Both require a 12V power source. I just use my field battery, which I charge with a regular 12V car battery charger. I don't have a charger that is AC, other that the car battery charger. I also have a 12V power supply from Radio Shack, but I've found the field battery works just as well.
