I am scheduled to have 1 hopper and and 2 Joey's installed on Saturday. After doing some research it appears I may be better off getting 2 hoppers since I will most likely be adding on a Joey in the future for my sons room. Does this sound like something I should do or just stick with the one hopper? Also I was told that there is a one time fee of $50 per hopper and a rental fee of $7 per month per Joey. Does that sound correct?Thank you for your help. I am trying to make sence of all this hopper and joey info.
