This meter sounds like a fun and useful project. Purchase one here–all proceeds benefit OzarkCon! Details below:

The Four State QRP Group is pleased to announce a new kit, the QRPometer, a sensitive and accurate power/swr meter designed by David Cripe, NMØS. Complete specifications, assembly manual, and ordering information can be found here ttp://www.wa0itp.com/qrpom.html
PayPal is accepted.
The range of accurate power easurement extends down to a low 100 milliwatts. This kit was conceived to fill a need within the hobby for an inexpensive, highly accurate RF power and VSWR meter for QRP power levels. With it’s large digital display it makes a very useful addition to your shack.
The QRPometer uses simple analog signal-processing circuitry to provide a set of essential measurement features not previously available in a single unit. High quality, double sided,
printed circuit board construction is used, with solder mask and silk screened component reference designators.
All components are through-hole for easy assembly. NO toroids are required, and all controls and jacks are PCB mounted. The QRPometer can be constructed by beginners as well as experienced builders. Construction time is approximately 3 hours, depending on experience level. The only equipment required for calibration is a digital voltmeter, and a QRP transmitter..
All proceeds go to fund OzarkCon. As always, thank you for supporting the Four State QRP Group. http://www.4sqrp.com/
UPDATE: See comments–first run of these kits sold out within 27 hours! More to come later.

Wow–I just heard that their first run has already sold out. Incredible.
UPDATE from QRP-L:
Sales for this kit have been incredible. The first run has sold out in
only 27 hours. We regret the neccessity of suspending orders until
after OzarkCon 2012. More kits should be available about the 3rd week
of April. Please monitor this page and the QRP email lists for the
resumption of sales announcement. We’re working hard to bring you an
outstanding conference again this year. Thank you for your patience
and understanding, and thank you for your great support.
I love this radio stuff !

Do not use IC sockets on this PCB, the meter display will not fit on top of the chip.
(they are difficult to remove again when soldered in place)
