I just went looking around, and thought someone here might find these items to be of interest. The Capons link of the Radio Shack web page has their telephone rfi filter, #43-150, for half price. There's also a battery charger Cat. #: 23-327 for half price at just over $6.00. It handles voltages from 4.8 to 9.6. I don't work there. Everything looks the same in Shrink Wrap!
