My motto: Dell sends you to the hell.
Because Dell is extremely unrealiable and poor quality.
Acer does also have it's drawbacks, but won't let you down.
A friend of mine had an old Acer Aspire 1400 (8 years old, I believe) and it still works.
The only broken thing was the touch pad, because of the Coke that was spilled on it (but every touch pad would fail if that happens).
Both Acer and Dell have it's own plus and minus. Acer laptops available cheaper than Dell . But i am suggesting dell which is more reliable and versatile. This i am telling from my personal experience. You can also try for refurbished laptops.
