If you're the hands-on type and prefer to build your own controller hookup panels, we've assembled a hardware kit which includes the basic components needed for any panel configuration.  There are several optional add-on's which allow you to design/build a controller hookup panel to satisfy your requirements.  The "Articles" section of this website includes links to step-by-step articles which describe how to plan and build "basic" and "enhanced" panels using the hardware kit and optional components.
