I have a Dell Inspiron 8100 that had a hard disk failure (read: locked spindle and fried motor due to spindle locking) and am in the market for a new one. I have seen the wealth of new and refurbished hard disks out there, all the form factors needed, and am trying to decide on one. I know I don't need anything extreme, 80-100 gigs would be perfect, and there are very reliable brands out there that have been refurbished. The question is this: is it wise to go for a cheaper refurbished drive, or pay the almost $100 more for a new drive? As for the ac adapter's failing, refurbished will do just fine after I get a couple of new batteries. Also, I am in the market for full upgrading to it in the areas of faster processor, socket 473, and better video. Any suggestions in those departments would be appreciated, though I would like to keep it limited to parts that would be the correct form factor of the laptop. Thanks for your answers.
