Actually, no, $400 won't get you a decent Cocker plus nitrogen and a good barrel. $400 will get you a Cocker by itself, which isn't all of what you need. If you want to just proceed within that range and be done with it without further spending, an Impulse or used Shocker will satisfy that specific demand. Perhaps $500 can get you a Cocker, barrel, and nitrogen, or perhaps with a fair bit of looking around such can be done with $450, such as prowling around scenario games or big tournaments for someone selling a backup gun they don't use or switching equipment, both of which happen a fair bit. Keep your eyes open and don't hesitate to take a good deal when you see it, BUT TRY ANY GUN BEFORE YOU BUY IT...THE VERY GUN ITSELF!!!
