I your a member of a club you need to try scopes in your price range. Most popular ones to get started in your price range (with some change) are
MTC viper (£120-150)
EB sniper (£180 ish s/h)
hawke sr6 (£60- £120)
You also have bushnells, Tac 30 and Leup's.
All scopes suit different eyes.
Try before you buy.
Hope this helps
