I think he is looking for a used, and cheaper, one.
No such thing as a "cheap" Aerotech motor.
Under Tripoli research rules you can fly a 4-grain, 5-grain or 6-grain AT reload in a Loki 75-8000 case with CTI spacers and hubcap.
LOKI
76-8000n case...-------$270
CTI Hub Cap-------------$50
CTI Spacer(max of 2)---$35 ea.
AT Seal Disc-------------$32
Aerotech
75-7680 Motor complete-------$630
AT Relaod Adapter Sys---------$99
AT Seal Disc --------------------$32
With the money left over you can buy a 6700+n AT M-1315 or Loki reload and have $ leftover, do the math.
Then you can fly AT, CTI, Loki and research reloads in one system!
