Thanks for the words of warning guys, I do appreciate that this isn't like trying to find a used pix recorder on ebay. However, it seems the Codex offers all the options that the SR-R3 was going to and it might be an option worth exploring. I've found enough information to confirm it will pass the 444 50p through one port without any IF box's. Beyond the recorder, I need the remote, Interface to F35, drives, and a dock to offload footage, could get very expensive very quickly. I think the F35 attachment is key to the codex actually being worthwhile on the F35, rec button, ramping, 444. I also feel like most codex-m recorders are now working with Alexa's and that mean's there will be plates sitting around. I've found a few rental houses that note it includes the F35 plate and the Alexa mount, so I don't think it's impossible to think it could be found for less than $1000, I know they were out there and I know that they aren't hardly being used now. I'll report back when I've got real leads, who knows, the ebay recorder could go for 10k still, but my feeling is it will be a lot less than that, and the recorder is the most expensive component (it has life beyond F35 use), but I also need to find a reliable source for a used F35 plate for the Codex before any of this dream can take form.
Also back to the problem of where to put the battery with the codex. I guess it would be back to the L handle and mount the battery on the top of the camera. But with the bigger codex setup, I'm probably on sticks, a dolly or a jib where a block battery on the base is the best option.
The more I use it, the more I want different configurations of recorders for my F35: a small hyper deck handheld setup, Odyssey 7q for steadicam and Codex when I want to get the most out of the camera. I wish there was one recorder to rule them all, but they all have cons. I also think speed ramping is a worthwhile feature to spend money on, even more than 12-bit, and the only way to get that feature is going to be the original tape or Codex because it needs the information passed through the dock, not just the SDI ports, so there won't be new options for a ramping recorder.
