We were in our local Rockler store a couple weeks ago looking at moisture meters. They had an el-cheapo from PSI for $40, the expensive one for $200 and the Lignomat for $115. The PSI didn't work for crap. No consistancy, hard to read and had to push too hard on the spikes and they were larger diameter. Their expensive one was more than I wanted to spend, yet it was not consistant. The lignomat was easy to read, came with two sizes of probes, worked every time and was consistant. It also had two settings which I need to read up on. I wouldn't buy the PSI if they paid me to use it. I look at it this way, if I am working something like mallee and it is going on a Statesman that I get $125-$150 for then I want something that is acurate. I don't want to test a blank and have it read between 8% and 12% and find out a month after I turned it that it was the higher end. The lignomat would read to a tenth of a percent. Well worth it in my book.
