Whether or not you should depends on the reasons you are thinking about this and how you use the car.
I do not know specifically about your car what this would cost but it depends the supercharger. How much boost are you looking for? This could run $2-10k including the supporting hardware that goes along with the supercharger, I would assume that you would be much closer to $2k though unless you are building a track car. Add to this the labor cost of at least $500 or more depending on your area, again I do not know your car specific so these are general numbers.
If you have not done any real work on a car, oil changes don't count, you should have this done. If you have done work on a car I think you should make your own judgment.
