Hi Chris
If you can afford it, and you intend to keep on shooting target pistol (good for you!!) spend as much as you can afford on a quality pistol. As you can see, I'm biased and shoot a Steyr LP10, but it took me seven years to save up for that. It's in immaculate condition, 13 years old and cot me just short of £500. The deals are there if you look for them. Any of the well known makes (Steyr, Walther, Feinwerkbau, Morini etc) will outshoot you!
Try and shoot as many as you can before you buy - most clubs will be only too happy to introduce people to their new toys!
Good luck, prepare to lose your wallet.......
