John,
For video work, the Evo over the Inspo is the way to go. Smaller, lighter, travels better, etc.
ISC makes a mini-Meg that is well regarded.
For me, because Cis-Lunar stopped 15 years ago due to venture capital issues, I chose the Inspiration over everything else because it seemed to be the largest company. I wanted some stability in the company whose product I chose. It turned out to be the right choice. They did not have the Evo when I bought my Inspo. Get the extended range Evo, which uses an Inspo scrubber. Get the temp stick, as I get 6-7 hours out of the scrubber now. Saves on Sofnolime and pays for itself.
Some guys swear by the KISS system, but really, between white balancing, macro, subjects, framing, manual controls, etc while shooting video, do you REALLY want to add additional task loading, especially having to manually control Po2 in a system with no warnings of ANY kind other than an additional visual display that has to be looked at every minute or you will go unconscious and die?
But with the partnering of DP Scandinavia buying Poseidon, then partner with Bill Stone of Cis-Lunar, I would give some LONG hard looks at that unit.
I have interviewed Dr. Stone twice now, HD videos of which are in the Cis-Lunar section here, and I am impressed. The 20 year old Cis-Lunar Mark VP still to this date has a combination of features not since duplicated, but now DP threw a truckload of systems engineers over to Stone and the new Mark 6 Discovery is revolutionary, using just two sensors.
The compact Sentinel is great for someone with more $ than God, and it is certainly a well regarded unit.
There are lots of other units, like the Revo, the Optima, etc, but for what we do, we really need a small, light, automated unit, and at $6500, the mark 6 will leave you with enough $ to put towards that Scarlet 5k videocam and housing
Hopefully some other CCR types will chime in here and add their opinions.
