This is similar to my previous comment about the vector impedance meter
market.  At flea markets, it seems paradoxically like a cable is worth
more than a power sensor which in turn is worth more than a power meter.
The opposite order of the original list prices.
These days, you can buy a decent power detector chip from Analog Devices
(possibly on an evaluation board) and maybe you don't need a power 
meter.
If you are below 80 MHz, Linear Technologies makes a thermal power meter
on a chip.
