Compaq? What the hell is Compaq? I've never heard of it...
I believe its currently owned by HP, its a budget computer division. Its an extremely well known brand. :o
They often create a computer design and then release it with several different versions, some extremely cheap with low end hardware, and occasionally they have higher end models.
I've always found them to be extremely affordable, reliable, and have wonderful customer service. You just have to spend time finding a good model.
