Cockers can be fiddly....
...worth considering on the "pick up and go" front are the Tippman 98, and possibly even an automag. Both fairly cheap, very easy to get on with and while they don't have fiddly electric bits to get in the way, both have the option of being able to get an aftermarket electric trigger frame. Oh and they both hold their value quite well when it comes to resale.
For tournament play, I'd go with the impulse....again easy to pick up and play, rapid, versatile, upgradeable and a good place to start out
If you have a little extra in your pocket, are looking for accuracy, good rate of fire, a bit of bling, and cocker-like performance without the fiddly-bits..I reccomend the Evil Omen, I just got one as a backup and it's lovely
