Piedpiper, You stated, "Again, the price of the P7 (current list - $2695) includes a dedicated external power supply that is more finely tuned than that available to the P3/24 and P5"
Who told you that the P7 has a "more finely tuned" power supply? This simply isn't true, only the P9 has this feature.
