I ask because I thought I read or heard that these were discontinued and I am not certain why. Was there a problem with them or were they just phased out in favor of the RKL and RKEs? The reason I ask is that I have an opportunity to purchase one of these along with the 8 socket brick and three 2 socket expansion modules for a really low price (less than $75). If the unit is no good then obviously, I don't want to waste the money. I'd like to hear your opinions.
