Using the market price of $70M for Q15 towers, the value of other quality towers can be calculated. For example a Q10 tower only produces half as much data as a Q15 tower and wears out more quickly so at half the cost it's a bad deal since you get the same amount of data and you have to repair it more often. To get the cost/MB equivalent to Q15 towers ($178/MB), you'd have to buy the Q10 tower for $28M which means they aren't worth more than that amount (they're worth less since the speed is slower which effects service level).
