cowface remember you should half the brand new value if you are buying a gun second hand,
i think if you look round, you will find a much better offer than what this guy is selling.
check the classified section here or ask at a local tourney
For £200 you can do much better than a blow back, you could get a mag or a cocker which are real tourney guns
anyway go and see a local tourney and count how many people are using spyders or pihranas..... none is my guess
