I agree with previous post - spend as much as you can afford on a decent modern pcp. A new one (Feinwerkbau, Morini, Steyr etc) can set you back over £1k but second hand ones come up from time to time at musch lower prices; you need to keep your eyes open. Try out as many different models as you can at your local club - you will find most 10m air pistol shooters quite accommodating and willing to advise. Good luck.
