When your laptop charger dies, it's always a mad rush to get a new one. I did a quick search to find a relatively cheap one and came up with this, so it does win on the price region.
When considering design, it must be noted that the lead seems extremely short, which is not great if you're one to move around a lot with your laptop. I often find that if I move to another seat on the sofa it will come apart between the part that's connected to the laptop and the actual charger part. It is really frustrating so it may be worth taking into considering how long the lead is as it may not be as long as the original charger.
However the more important thing is how it works. I find that this one is far less hot than my last charger, and I have had no glitches involving wiring or general working issues and I have owned this one for around a year.
Of course, I'm sure I will have to buy a new one in a year or so as laptop chargers simply do not last if you use them regularly. I think it will be worth trying to find one with a longer lead but if that fails this is a definite winner because of price and quality.
