Hi Tonyw and welcome to the forum,
I'm sure there will be lots of advice coming from members here, but my tuppence worth is find a club, join and use their club pistols for at least a few weeks, then you'll have better idea of what you want, what you want to use it for, and possibly even find out who has what you want for sale locally.
Its very easy to buy the wrong thing at the wrong price when you are just starting out. £350 spent on tat is £350 wasted.
Cheers
