Sold three 580's and two sets of RP PX for $ 1500, bought three 600's for $614 each. Then with double rebate added two more 600's.
Mainly for integrated radio. Save a lot of space in case, less time to set-up and no fiddly brackets, Velcro, etc.
It's so easy to use, I hardly had to check the user manual.
Costs less that a 580II with either RP or PW receiver (except non-ttl).
