I'm the same my dad swears buy it, i tend to prefer a store you can walk into and check its right etc, Worth a look though dude, sony Vaio charger went duff in work, one of the women ordered a replacement from ebay and it only cost her £15 delivered, works fine, only took a day or two aswell.
Try ringing local shops like the Den but in past experiences they are pretty specialist and hard to find in a physical store
