From there on out I would avoid WDMX as the plague, try to use cable as much as possible, if that is not possible then use this product since it is the most solid for this type of environment.

Don't disagree completely and I would definitely avoid all of the rip-off brands, but this one is solid. It's what's built into the newest ETC lighting fixtures:

Multiverse® Wireless DMX/RDM (citytheatrical.com)
