@~AyaMachi~ I'm the same. £10 credit lasts me 3-4 months.
I'm not sure about Acer. I've worked on plenty of their laptops in the past, they're not the easiest to work on but not the worst either. Generally the specs are very good for the price but the build quality is amongst the lowest to compensate, they clog fairly easily and the fans aren't much cop. That said, most consumer laptops are a pain to work on compared to business laptops which are usually fully modular (I used to work on IBM thinkpads & they were wonderful, even the power socket was modular & you didn't have to faff about getting to anything.)
