This is my 2004 Prostock WGP Autococker. I got it from someone on craigslist for only 65 dollars, so I don't know if I can consider this for the 350-700 dollar range... but I have since added quite a few upgrades, and I definitely put autocockers above the spyder/piranha/etc. club... I shot spyders and piranhas for a while and they don't compare when it comes to accuracy and reliability. Don't knock autocockers... They are amazing for those of us that know how to properly time and maintain them. There's nothing like the sound of the three way and the back block... so smooth and light feeling.

-Stock trigger/valve... but it's timed with very small trigger pull

The third image is just another picture of my compressed air tanks... and my cousin's autococker (chrome) don't worry about that, I'll post that later for rating.
