Question on RIO Option....

What are you guys using to replace 1791-8AC units in the field. I think these units are getting phase out and they are price ridiculously high $1550.

Do you guys know about another RIO alternative. I'm using a SLC 5/04 with a 1747-SN scanner.

I'm using Bechoff, find e.g. BK5250 for BK9053 in my drw.
Their have good prices!
