Don't forget no matter which brand you choose, make sure you have a "play" and see if the shape/weight is good for you. If it feels comfortable, that's half the battle. Price is not necessarily and indicator of quality....there are some great irons out there that don't cost the earth. I currently have a Philips and it is really efficient. Mine has a calc clean system which stops it gunking up with hard water and it also switches off automatically if left unattended (I am inclined to get distracted). I had a Rowenta and it behaved very badly - spewed "rusty" water and the bottom dropped off after about 2 years. I always tip the water out of the reservoir every time the iron is off for a long period or being put away in the cupboard.
Chasing Hawk is right.....nothing you buy new today will last as long as your current one. Unfortunately it's that way with every bit of household equipment.
