<html> <body> Dave, I recommend a heavy steel fork for stability and long ring time.  Mine was bought from Renner years ago - don't know if they still sell it.  Made in Italy. Any of the better steel forks are reasonably stable.  If you are being very careful the fine few 10ths of a cent accuracy, your best bet is to  tune it at a useable temperature, then get used to testing the temperature each time you use it, warming it to pitch.  During cold weather I used to hold my fork under my arm while getting the piano ready, or carry it on the inside pocket of my coat.  Testing the temperature on the side of your neck seems to be pretty accurate to make sure it is at temperature. If you have an aluminum fork, just keep it as a novelty.  If you have a small steel fork, tune it (by filing) to a precise electronic machine at the temperature you can duplicate in the field.
