ebay used to be a good source for x-10, but now all you've got is bunch of professional x10 sellers on ebay who just clog up the listings with endless auctions for the same x10 item, and by the time you pay for shipping ---(this you have to watch because there are sellers charging 2 & 3 times too much for shipping just to pad their profits)----it's usually more than what you paid from x10 or smarthome or one of the other e-retailers. I would like to see the professional sellers get their own half of ebay with the individuals who just want to unload some extra stuff they bought, having the other half. then, like spam you wouldn't have to eyeball it if you didn't want to...
