Heres a thought a guns design fault can leed to it beinging a collectors dream . Take the 300r mine works faultlesly . I conceed that the probe does seam to be a weaknes that wont tolerate misuse . I asume that is why the design was pulled but like the Air logic Genesis where it never sold eell because its nigh on impossible to cock and a Jackel where upon the qaulity was doveose compared to its german counterparts. These gun as the same off many more are now considered as real colletors guns where upon there value is hight . I agree as already said that it depends how much some one is willing to pay . But I concider my 300r at worth more than £300 .
