Another option is the LP100, it's available as a kit or ready made
http://www.telepostinc.com/lp100.html
it's pretty easy to calibrate the kit accurately for SWR, accurate
absolute power calibration may be a little more difficult if you do not
have access to a good reference power meter or you can have your kit
calibrated if you post it back
I am really pleased with my LP100
