My parents live in an area where they're in one major metro's DMA, but are actually physically closer to a smaller city with its own broadcasting area. Anyway, they've always got the networks from DirecTV from the major metro, but also used an AM21 to also get the channels from the other city. Anyway, my dad went to watch something on it last night and noticed it was not working. I walked him through the troubleshooting steps (restarting receiver, trying to redo initial antenna set-up) and nothing helped. Anyway, I just assumed the AM21 had gone bad, which has happened before, and told him I'd get a new one and install it for him during the holidays. Well, went to order one this morning from Solid Signal, as I have successfully in the past, and the only available options are $150! Did a web search and they seem to be selling used units on eBay for $100+. What's going on? Last time I purchased a few years back, I think they were $50-$60. I know DirecTV hasn't been sending them out for a while, but they were still available, last I knew. Anyone know what's going on?
