I couldn't agree more EBi. I've been installing SymmetrE/EBI since its debut with R100. My clients and I absolutely love it. Most of the trouble lies with people trying to use it without either the proper training or their egos not allowing them to follow instructions. Its bad rep is mainly attributed to word of mouth "sour grapes" attitudes.
EBI when installed correctly works great. Most complaints come from poor installations by untrained people. It's a powerful tool when setup correctly.
