Most of the time we buy what we decide we can afford at the moment.
If you can afford to throw in extra
$150 to
$250 (and plenty of choices in between) I would do just that, and get a brand new laptop with more power and better features. If you can wait, then do and keep an eye on sales events, look for rebates etc.
Buying a used laptop is a pretty risky proposition and I would not do it unless I knew the individual laptop pretty well. Market value of the laptop you described is no more than $150 (if that)
Also, consider these factors:
- a celeron is pretty power hungry so the battery time will be significantly shorter than with centrino
- laptop batteries have a certain limited life, i.e. number of charges they will take. Usually that will be around 500 times, so a two year old laptop battery will hold charge for maybe 30 minutes.
- by the time you add extra memory (which is a must) you will have spent closer to what one of the brand new laptops linked to (above) will cost you, but you will still have godknowswhat.
- only rich people can afford to buy garbage
good luck.
