Anyone know of an infrared hand held device that will allow changing the price and time on an older Fragramatic vac. I see lots of them for TVs and stereos for sale in resale shops. I still have the original 75 cent start up price and am raising all my vac prices. Just wondering if one would work and the sequence of numbers to push to reprogram the timer. Sounds kind of crazy after I typed this. Or maybe someone has an old controller for sale? Jerry
