Is the ACER Aspire a good deal for the money? I found one with 3GB and 160 hard drive.?

IT has all the features I am looking for and does what I need it to do such as burn movies and cds and download. I just don't kow about the hard drive size or the 3GB. It's priced at 700.00 and I need to know if it is a good deal for the price. Thanks
