What jacks do you guys use?

My V10 is stock height but even then my 3 ton hydraulic jack still doesn't come close to lifting it. I have the original factory jack but those things just make me nervous...even when only lifting it to put in on my jackstands. I am looking for something that I can throw in my toolbox and use when changing a tire on the road. Hydraulic bottle jacks seem to lift high enough and are small enough to put behind the seat of in the tool box, but they don't seem much better than the factory jack. So, what do you guys use?
