My wife and I were wanting to update our kitchen with a new sink. What we wanted was a 50/50 bisque drop-in. We shopped at some of the building supply stores in are area, but they only carried black, white or stainless steel. We found just what we were looking for on Wayfair.  
The installer did have to make the opening on our countertop a little larger, but it looks great. 
It also had the strainers included with the sink.
