Edelbrock Carb-Electric vs. Manual Choke

I never would like a constant voltage draw in a device for the entire trip for something that only gets used 2-3 minutes after startup.
Where are the manifold heated chokes gone these days?

(I don't use a choke on my setup because I use LPG which idles fine at pretty much any outside temp.)

Agreed-would rather have a manifold-activated choke. BTW-Like an ignition coil, the draw only occurs when the key is turned.
