Or better still, both: I like the Drayton wiring centres (only about sick
squid from bee and queue) since you can see what the links do (unlike the
honeywell PCB types) but they make it fairly idiot proof, both for you when
you're wiring it all up at the end of a long day/week and your brain's
already clocked off, and for whoever comes after you. Don't you hate trying
to debug a mass of spaghetti crammed into a single socket box? :-)
