YEa I'd look at that Gateway posted... I just bought a laptop from Best buy after doing tons of research and bugging my IT bf constantly with questions, they have all kinds of price ranges there .. and the staff can be very knowledgable. Tell them what you are using it for most and they will recommend something in your price range.. they dont work on commission. They will try to sell you the maintenance and protection plans though. I would recommend Windows 7 though, I've had it for 2 weeks now.. no problems. Vista is another story.. try not to get vista. The Gateway has Windows 7. I ended up with a Sony and love it. Also if you are willing to stand in line on Friday there are some GREAT Black Friday deals on Laptops at Best buy... Also go online and look up the model you are considering and read the customer reviews.. that can tell you a lot. When you look at the laptops at best buy you can get ratings on the laptop and compare right there in the store... they have a rating system that rates the speed, processing time, etc... it helps if you are comparing a few models and might help you narrow it down if you are torn between two. I was torn between a Toshiba and a Sony.. the Toshiba had a much better warranty but also had things like a fingertip reader that I didnt need or want. The Sony had blue ray but speedwise both were compatible so it came down to reliability, feel of keyboard to me for my choice. Really what you are using it for should tell you the most about what you need .. no matter the price range.
Good luck!
