I have one, but its not a newer one, you can buy and install yourself, they are capped at 20 bps now but the older frames were capped at 13 bps, and batter life is crazy, no eyes means alot les power needed, also no solnoid helps too. We are talking like 50,000 trigger pulls per battery. But you said you wanted soemthing cheap,a dn these things are still runing like 400$ new, I might be able to sell ya a used one is your interested though. PM if your interested, its in good care.
WHEN YOU SEE DEM BOYS ROUND YA WAY HOLLA DAMMIT MAN
