GRE Prep

[luke77]

So I thought this would be the most-asked question on here, but I did a quick search and didn't see anything directly addressing my question. I'm wondering if there are any good, free sites for GRE prep online that you guys would recommend? Also, any book recs for GRE prep? Finally, if I order a book does it really matter if I get the newest, "2008 edition", or can I save some cash and get an older edition off ebay or half.com?

Thanks!

I looked for great online sites, I couldn't find anything worthwhile. I settled on buying three books just so I would have access to all their online tests (Princeton, Barron, and Kaplan).

They have added a new question type or two, so I bought the 2009 editions just to be safe. But I can't imagine it would make that much of a difference to have a 2007 edition.
