Just FYI, I am selling a Innovation First Victor 883 Speed Controller on ebay right now for fairly cheap. I just thought I'd give your tank guys a heads up because I know that some of you guys use these types of speed controllers for your larger tanks. It's very heavy duty. 24V 60A. Let me know if you have any interest.

Thanks for looking
