Which Zwave Alarm Control Panel to opt for Dz?

[kimhav]

There are several threads talking and asking about which alarm control panel/keypads (also ref. to zwjs config DB) that Dz supports and what to opt for. Also, when searching for never devices which supports S2 security the list seems quite short. So what devices are there which supports S2 security? Currently one of the never devices would be the Ring Keypad v2 including the BeNext WTRFID Mini Keypad and Z-WAVE 700 Keypad; but what else are being used and tested by the Dz community?
