Benjamin Maximus Euro. AEAC has an excellent review. Cheaper than a Disco. I have both and the Maximus is a great rifle. Hand pumping isn't bad. Bought a TAO USA pump via Amazon, and it works fine.
Check out a RWS Hammerli 850. Uses CO2 cartridge, you get lots of shots per cartridge, and it is easy to fire. Plus, light and has an 8 shot repeater feature. My 7 year old loves it. And so do I. It is simply fun to shoot.
