okay, i'm still a little confused. our basement is nice, but i'm not sure i'm up for spending the money, nor do i want to have to install a keypad. the x10 sounds like the way to go, but what all do i need? I need the switches and the ir543? is that all? i also forgot to mention a very important fact and that is that two of the switches are 3-way, they can be turned on and off by a couple switches on the other end of the basement. What do I need for those, can I leave them the same if I don't need to be able to dim them from that side of the room?
