well its all relative. generally the parts put on these upgraded guns can be worth more than the actual gun. if you trick out any cocker body it will be worth 300 in just parts.
....considering a rare or desireable cocker body will be 300 alone. or you get the oh so typical 03-04 prostock body blah.
but a standard lighting with a economy pump...no not even close to 300. unless it had full ccm AT pump kit and some nice internals, i wouldnt consider spending over 200 for one. but thats just me.
