Regarding the FWB65, I will say I am absolutely devoted to it, I am sure it is more accurate than 99% of shooters, but unlike some pistols it will punish poor technique. It seems that with mine I can "feel" the shot; if I do my bit, I can feel that it's going to hit the centre, but if I don't do my bit then it's not just a miss but a big miss. I wouldn't swap mine for anything though.

If you don't mind CO2, look at the TAU7.
