Likewise, I have a 2008 EX8 which is quite literally one of the best things I have ever bought!
Absolutely love mine, the only problem being (which I've mentioned before on similar posts) is the wheel bearings which are not particularly well sealed. The rear isn't too bad as the cassette protects the hub to a degree but I've found the front wheel to almost seize up after very wet rides where I've been through axel deep puddles. Obviously, I try and avoid that as much as possible now but will replace the frint hub at some point in the future! It may be something that's been fixed on 09/10 bikes but be aware of it.
I wouldn't worry about the chainstay breakages – as mentioned it was an issue on a few first production EX's in 2008 but was quickly strengthened. It won't be an issue on 09 bikes.
