ED makes a prett good product, but I will never buy from them because of some extremely shady business practices. You can look on sounddomain.com and caraudio.com and find many horror stories about their customer service. Just look at the delays on thir new gear. People had it pre-ordered for 8 months or more with close to a dozen delays before anything was shipped. Also if I remember correctly the first batch of nine.1's had about a 75% defective rate.
