    If you accept the theory that something is better than nothing, for the money you could try this one from HF. Mine isn't under $100, but you could check retailers that sell Delmhorst meters. Or check Ebay or CL.

      The electrical resistance of wood varies with its moisture. Drive two sharp metal pins about 30 mm apart and about 10 mm into the wood. Measure the resistance along the grain (lengthwise).

      You can also cut a piece off your wood, weigh it, then dry it in an oven until it stops decreasing in weight. Then you will know precisely how much moisture there was in your sample.

      Bill,
      The internet, the gods gift to plagiarists.
      I expect that this one would be free.

      Bill, over here in the sun
