TRNW-2: Ultrasonic Cleaner

[Steve Everett]

    Yes,  I know Todd and have his cell # if it hasn't changed from 5 or 6
yrs ago,  I had heard he was going to continue the techms,   they just no
longer supply WIT with them I don't think ?   my only issue is he's on the
complete opposite side of Atlanta from where I am or where I work,  so it
makes getting a techm from him difficult on the rare occasion I do need one
