About 4 years ago I bought a Powertap wheel from Neuvation for what was at the time a fantastic price: $900 without a head unit. The hubs were, at the time, selling for over $1000. So a built wheel for $900 seemed like a fantastic price.
For years Cycle-Ops had the market pretty much to itself, and the prices reflected it.
Imagine then my amazement to read on DC Rainmaker that Cycle-Ops has cut the price of their wheelset to $1000. For that price you get a 1800g wheelset (not light, but then again it does have a powermeter attached). Even better, you can get it for $900 through that blog's affiliation with Clever Training (code DCR10ZTG, apparently). Of course the hub has ANT+, and will work swimmingly with your Garmin computer.
For once, this leaves Neuvation looking almost pricey, at $849 for just a rear Powertap wheel.
I imagine this is the inevitable result of the plethora of power options that have come on the market in the last couple years. Pedal based systems, Crank based systems, heart-rate strap based sytems. There's even a handle-bar mounted powermeter that uses airflow and a gradometer, which name I can't recall. Of all of them, I still prefer the hub-based powertap, since it's trivial to move it among bikes.
Anyway, I don't really have a point here. I was just surprised at the price drop, and wanted to vent.
