Sounds like the general consensus is that, with upcoming technologies like LED, it makes sense to pay a bit more for some of these improvements, but not upwards of the cost of the Planar PD8150. One thing I also watch for is cost of replacement lamps. Lamps for the JVC's cost big $$$, but lamps for the SP8602 can be found for $155 shipped. Not sure about lamp costs for the Optoma 8600 or the Planar PD8150. The bottom line is that with upcoming LED tech, people are less able to justify buying the premium current tech, and the SP8602 seems to make a lot more sense than others right now.
