Hi George, W1ZT, I have a Kuranishi BR-200 and an MFJ-259B. Both are easy to use and seem to give about the same results. I prefer the Kuranishi. It seems to be a laboratory grade instrument. However it only gives Z, not R and X. It comes with a very nice 50 ohm, SWR=1.00 test load to calibrate it. Worth a look. 73, Alan, W4LKE
