Probably the same, assuming you got it from a reputable site/dealer at that much reduced price.
How long since you last used Elements? It was first developed to test out the new GUI for Photoshop many, many years ago, so any recent version of PS should look fairly similar but with more detailed dialogs.
There are several good sites for PSE tuts. I'll post a few later but you can always just search for PSE and tutorials.
BTW, I think 10 is the best version yet, even 9 had bugs and they seem to have killed those and got them act together quite well, now.
