I'm pretty set on using Leviton 16400's in the bedrooms because the switches there normally just control an outlet anyway, can just use a lamp module on that end.
For the fixtures, i'm debating whether to just go for the switchlincs, or get the more affordable Icons.
I use pure x10, no insteon, and I do all my scene/macro programming on the computer end of things (don't care to program light switches)
My needs are 1) transmit x10 status on local control 2) respond to status requests 3) be able to disable preset dim on dimmer switches.
Looks like they both meet my needs, it's just a matter of how much extra insteon fluff I want to pay for. Although the light pipe color change kits and paddle kits look pretty cool...
