I use a "Slime 40026 2X Heavy Duty Direct Drive Tire Inflator" pump that I found on sale for $60. The power cord is short, but the hose is long (it takes a really heavy power cord to carry enough current for a 12V pump, that's why it comes with a long hose).
I tried using a cheap cigarette lighter pump and ran into the same problem as you -- it could barely make it over 70psi, but I needed to get to 80psi.
If you get a 12V pump, get one with battery clamps, not a cigarette lighter adapter, the cigarette lighter can't put out much current, so those pumps don't have a lot of power.
If money is no object, ViAir has some great 12V pumps, but they are not cheap.
