It is always interesting to see people's opinions when discussing equipment and technology. Lutron is a good complany as with Vantage and Lightouch. It really comes down to the business side and your market... who has what etc... and of course your capability. That is the real question! Are you capable of delivery or are you going to create a monster that you cannot control?

Do not forget the first interview is for your benefit also. Feel them out carefully!
Who else is bidding? etc....
