If you want the best, you should be looking at Anschutz or Feinwerkbau. Personally, I'm on a more restrictive budget and purchase my rifles for their accuracy per dollar spent. This means guns like the Air Arms TX200, Hatsan Galatian, Umarex Gauntlet, and Air Venturi Avenger. I can hunt with these rifles and compete against my friends with confidence right out of the box.
Although the FX line is popular, I'd ask an FX owner what upgrades they did. I think you'll find that they usually put a lot of money into them after the purchase. If you love tinkering with things, then you're on the right track. Myself, I can't afford that.

My WC3 is superb fits me like a glove- nice and light and suitable for off hand, I think its worth more than wheat they sell it for new.

Also does a 4fps spread so is very accurate.

My Daystate Pulsar HP needed a scope and out to 100 yards its perfect, oh yes I have needed a ton of .22 pellets too!
