I have no idea what the price, my ballpark price would be about 40K, +/- abt 10K I think there is someone here with a 6620, but I haven't seen a lot about the RX series here.
BTW, its KIOTI, as in the animal, not KIOTA:thumbsup:
When I priced a 6610 last year it was right round 35k. I know it's not the one you're looking for but with all the kiotis I priced I'd have to say 45k.
