STS,
Thanks for the reply. The $43k is for everything listed in the package not just the shell. We figured the pool would run us about $40k total. Also here in the Washington, DC Metro area everything is super expensive.

We too have rock in our area and will be sure to speak with the salesperson to see about a fixed cost for excavation. The first two contractors coming to give us quotes are located near my house so I'm sure they understand the type of excavating issues we might have.

Thanks again,
Bill
