I have tried a couple simple ones. I have know idea what they would retail for. The ones I used were samples from manufactures for trial purposes. For one thing the price has dropped considerably in the last couple of years bcause of technology improvements and the ability of the badges have gone up. I have not used one of the badges that you program on your computer, just the ones you program using the buttons on the back of the unit. I was always playing with the speed, trying to find a good comprimise between being slow enough for most people to read and yet fast enough that you are waiting around for people t0 finish reading your message. The ones I tried used a rather large flat battery that lasted well if used for shorter periods of time (less than an hour or so at a stretch) but if used continuously would onlt last about 4 hours, maybe a little more.
