Ref post 11, bought my acer base unit from the same firm as yourself,had no problems whatsoever.
Have just replaced my laptop and was going to go back to them to purchase one.
Had a final trawl through the web, and ended up going to John Lewis, where I purchased an Acer 5742Z for £399 with 2years warranty.
Intel P6200 processor-4GB memory-750GB storage-home premium.
Not being a geek,took a chance with this one,but compared to my old one,its a racing machine.
