I would go for the 12V to 24V cigarette lighter cable.
It's an energy equation, with the 12 to 24V method only using some energy, but if you use an inverter you do go from 12V to 110V (or 220V Europe) and back again to 24V. The latter uses much more energy and you will loose energy too, by heat generated by the inverter.
Last time we did have to inverters on board: one generated 120 Watts and the other 150 Watts (both 220V): only my iBook G4 and an external 8" TFT were connected to the 150W converter. Though there were no problems with the generated power, both devices did work perfectly for several hours a day, but when outside temprature climb to 30 degrees Celsius, the 150 Watts inverter just switched off because it got too hot, after 2 hours. The other 120W inverter just made it, though it dissipated a lot of heat too.
Now I use the Networx 12V to 24V car adapter, which won't get too hot and works perfectly for many hours. It is connected via a cigarette light adapter, a second adapter give the power supply for the above mentioned 8" TFT monitor.
