X10 replacement?

["RickR" <info@xxxxxxxxxxxxxxxxx>]

So many systems, and not enough time to play!

Everyone wants to be the X10 replacement but who is the closest?

I'm looking for:
* Cheap to start. No central controler at $500+ and not huge for a
simple retrofit. What is the cost for a single dimmer and 3way pair? (I
once saw a retail price sheet for Lutron RadioRa that listed a single
basic dimmer at $395.00. I laughed so hard it hurt.)

* Flexible! Must be able to grow a system to handle a whole house of
lighting, devices, and timers. AV control integration, security systems
and all of that should be possible. I'm biased towards lighting control
but the ideal system covers it all.

* RELIABLE of course, itherwise I'd just stick with X10! Everyone
claims to be reliable but only a good track record counts as proof. Hot
new products come and go every day!

Let the ranting begin!
