Well, my choice in PB's was reaffirmed today. I asked our salesman about changing from the IC20 to the IC40 and he informed me that we would be getting the IC40. It turns out they don't even carry the IC20. As he said, and you all have pointed out, there is very little difference in cost and they just didn't see any reason to offer the smaller unit.

I hope this is an indication of things to come.
