WWSRD?

My Dell Inspiron laptop, which I do basically all of my work on, typically has a nice warm white light on the front when it's on or plugged in. Earlier this week I awoke to find a blinking red light where the warm white one usually is. At first I thought, 'Oh, that's pretty cool my computer knows it's holiday season. It must be blinking because it thinks it's getting new software or something.' Well, I powered on my laptop only to discover that the blinking red light was not a season's greeting but instead the indicator for a 'Permanent Battery Failure.'

Long story short(er), my computer doesn't recognize the battery and if the AC chord comes unplugged the computer turns off and all work is lost - ask me how I found that out ;) Dell recommends replacing the battery with a suitable Dell unit; which naturally can only be purchased through the Dell website. Dell will ship the replacement battery to my door for about $200.

So the question to you, our wonderful readers, is: Should I purchase a $200 battery from Dell or go with a more economical battery that doesn't carry the Dell name?

What woud senioritis readers do?

All input is appreciated ;)
