Does anyone sell 2 meter beacons for propagation? 
I can find sources for Fox Hunt beacons but nothing that transmits more than a few milliwatts.  I'd like something between 2 and 10 watts.

I really don't want to build one.

Unfortunately for you, most beacons are homebrew or modified commercial rigs.  Kanga US sells a kit that can be used as the basis for the beacon, but you still need a keyer and small PA module.

If I were in your shoes, I'd try to find an old all-mode rig with reasonable stability and run it at low power.  I own three 2-meter all-modes, and none cost more than $75.  You might also be able use an old HT and key the PTT line only, but depending on the radio, it could be pretty trashy.  It would be best to use a crystal rig if you do the keyed PTT route.  Even then, you'll want to monitor it carefully to make sure you aren't trashing the band.  It may require modification to "soften" the keying.

I made my own as well. Very resonably priced. Check out my website: http://users.wbsnet.org/n0yk/beacon.htm
I'd be glad to help you set something up or build for you. Just let me know.

The Hamtronics T301 or TA-51 exciter kits would work for a CW beacon
in the 2 to 3 watt range. (They are designed for FM, but can be adapted
for CW.)  They also sell amplifiers to give 15 - 20 watts output.

However they cost more than a used FM mobile rig (and many new ones.)
