Liverpool,
I can ask hb abt my energy saver since he returns from overseas liao. I think he still has the supplier contact & price.

Ya, i also off main switch for everything, other than fridge. Really saves lotsa elec for appliances on idle mode. Even for xmas tree, i also bought LED fairy lights as it consumes lesser elec.
OC,
