Installing a water softener for well water.

When my house was built the well water was tested and was found to be on the hard side. I think it was somewhere between 8-12 dGH which is considered to be slightly hard. Well, it does tend to make cleaning of bathtubs a little bit harder and I have a difficult time with scaling of the desert spring home humidifier. I will be installing a new water softener but with all the advancement in water softening technology, what would be the right one to choose? Should I investigate the salt-less water softener?
