Cheap Enet IP PLC

I am looking to make a small stand alone machine PLC that Would have local IO say 16in 16out and have ethernet IP to communicate to a Proface HMI. I would like to stick with enet IP for flexability, anyone have any suggestions for an AB plc that would be a cheap good choice?

Allen-Bradley Micro850. It has been recently released and the Connected Components Workbench (CCW) configuration software is free.

Otherwise CompactLogix 1769-L23 series probably will do, however you will need RSL5K at least the Lite edition.

I have been looking at the 850 and looks interesting do not have any experience with this one but I like it. I am going to investigate this more.

Thanks!

Doesnt look like the 850 is available yet, anyone know when it will be released for purchase?
