Mines Zero : ) have a well , screw water bills!
I'd rather have a water bill than crappy well water any day!
I don't have to deal with a water softener, my water doesn't stain my clothes or my sinks, tub, etc. It tastes better, and all of my fish do just fine in my city water. What else am I forgetting? I've never had to buy/replace a water softener system, or replace an electric pump (for the well). 
There's pros and cons for both water sources. My personal views are thus:
I grew up on city water but now have a well. I much prefer the taste of city water...yes, I like the chlorine taste

but my well water tastes fine as long as the softener is not low. In fact, when I go to my sister and brother-in-law's house I prefer to drink the water from the tap instead of through the filtered dispenser in the freezer door

Staining clothes does not happen with a softener...on a straight well possibly, depending on iron content.
Staining of tubs, etc can also happen but if you use "Red Out" softener salt, that is reduced.
The best part is I do not have to put up with the corrupt Detroit City Water Department.
