I used to use a portable unit that I bought through Camping World (http://www.campingworld.com/shopping/ite...ioner/6848) that required rock salt be added about once a week. That was a PAIN! The unit worked but it was a fair amount of work to lug home big bags of rock salt and stuff the salt crystals down the fairly small opening in the top of the water softener.
