A 4 day class? Is that the one where you go to the HQ to learn about there higher end line. After the training you can purchase some items other EC's can't? If that's the one it might be good.

The most I've done is a day here and 1/2 day there localy put on by the supplier. It does not hurt. Something I don't like is it's 1/2 training and 1/2 selling you on the products. Never seems like they get deep enough in the training for me. More of a product overview and features. Some of the local training was done by a maketing company. So you have a sales person telling you how to hook them up and sell them.

Sorta like I know how to hook up a Maestro dimmer but never really figured out what wire does what to make it work or troubleshoot.
