Harvey Norman are currently doing a 'buy one laptop, get the second half price' and I wondered if there are any recommendations from people here as to some good laptops.

Probably looking at a 15.6" screen, but doesn't need to be anything fancy. Probably most important thing is that it's going to last 3 - 4 years. 

Anyone got a couple of model recommendations worth checking out?

TIA
