Thanks. Got a dozen of these, for $1.40, shipped. What a bargain!

I did too. You just have to be careful to use them correct side up - I believe the correct side for a TO92 conversion is D-S-G. If you solder the FET to the other side the pinout is different. As these boards are so small, I had to use a magnifying headset to figure that out....
