I just saw yesterday that CleverTraining is selling P1 pedals for $399, which seems a pretty good price for those not wed to their current pedals (or who are already using compatible cleats).

I got a pair of Assioma Duo this past Spring, and think they're awesome. I've had both wired and wireless Powertap wheels over the years, and always disliked the limitations, specifically in that I have multiple bikes and wheels sets, and invariably something wouldn't match up when selecting the bike, like the wrong tire on the Powertap for the ride, wrong cassette or whatever.

These Assioma swap bikes effortlessly, so for my needs, there's no better power meter solution (power meters, plural, yes, that'd work!).
