Thanks for helping me put my thoughts into words. You are absolutely right about the non-existence of a concrete list. If there were one, we would all have identical PSK's. My thought was to tap the experience resources of the group in order to provide the lesser lights (myself included) with alternatives, so that as skill, circumstance, and personsonal finance levels change, we could be reminded of options that hadn't occurred to us as individuals.<br><br>Alan
