We were also caught without power for several hours but being avid campers we don't have to have much power.
You could consider a generator like one of these http://www.hondapowerequipment.com/p...&category=play
We have the 2,000 watt version and it works great in an emergency. I am looking to mod out my electric panel to allow me to connect this unit, in my soon to be built garage, to power whatever we choose. This obviously has to be done with some reasonable consideration but will not come close to the cost of a supercharger. Also if you go this route you have to throw the main breaker or you will attempt to power the neighborhood or shock a linesman.
