Calling around for pricing was a little discouraging as the first places I called did not sell to homeowner's, just suppliers. I finally got an answer of $80/square foot from Grantops in Fredricksburg, MD. The bad news there is that is was for a green soapstone and that's not really what I want.
Compared to the quote of $45 for absolute black granite (this included measuring and installing), the soapstone was coming in at about double the cost. The good news is that I budgeted a lot for counters. I don't know what I was thinking, but I budgeted for $100/square foot. Maybe I just thought I had more space?
I guess we'll have to see what other parts of the kitchen go over budget before we can see if the soapstone is in our future.
