Hi Doubleriflejack,

I just bought the second edition (late 2007) more as a reference book but it was very hard to obtain and had sold out at the time in Australia and had to get one from H&H in England but it was very expensive via tem as you can guess. I think it is a great book but I sent an Email to Graeme Wright who said that with a bit of luck, Edition 3 will be out later in 2008.!! If you wan't to check when, Email him on: thepilotgw@hotmail.com

As I use it stricky as a reference book and can not comment on Vs 1 versus Vs2, sorry.
