It must have been sitting on that shelf for 10-13 years? (or, more likely, sitting in a warehouse or backroom).
The value on rainmakers dropped when ActionVillage sold off its entire stock about 10 years ago for $100. Since then, $100 has been the standard price for a new, or like new rainmaker.
But thats only important if you want to flip it. Wicked fun guns to play with. Essentially they were the first "electro-cockers". Great to tinker with. Very easy to convert to pneumatic-trigger, or even pump. (The base gun is a Sterling/Vector). The HP and LPR are not the best, but trivial to replace.
