I have had a desktop and three ACER laptops not a one have been junk. Granted two laptops were netbooks so they suck pretty much anyways, but they were well held together and worked perfectly fine. The laptop performed well and worked wonderful. They are cheaper because big PC names like Apple, Dell, and HP charge more for their products because they are a well known brand name. They know people will just buy it anyways cause it says that brand even if they don't know any better. When I shop for laptops I personally refuse to consider HP, and only takes me a second looking at any dell to decide its also worse. My preferred choice for anything under $800 I would say is ACER.
Sounds like a simple enough system. I will look for something non acer in your price range.
