BRS did a 15% off on all ecotech stuff a few months ago. I think it was their memorial day sale. If you did a group buy at that time you got an additional 5% off on top of that. If you snagged that sale it would have been 520 out the door for a radion. They do 10% off all the time, which would still be 585 out the door. I would gladly pay 35 dollars more to get new over used. I personally think any piece of electronics be it a sound system or an led light should NEVER cost more than 70% of retail.
