I think it is a bit pricey.  No mention on the fuel tank age, a major issue with O-2's.   Also, how are the wing attach points and is there much corrosion?  Those are things I would look into before I bought an 02.  Also, are you gonna fly it in US or Canada?  Make sure it can be US registered before you consider it as well.
My company does pre-buy inspections and if you like we can check it out for you.  Give us a call M-F EST 336-625-4731.
