Price is with transmitter or without?

Just the computer.
Transmitter is extra.

I wish. I could've gotten my gear a lot cheaper then.

I'm looking at replacing a 10 year old Oceanic OCi with a new computer. Discovered that the MH8A transmitter I still have is compatible with Shearwater so their products are frontrunners, particularly the Teric and now the new Tern. Given the age of the Teric, it's often always on sale, so there's only a couple of hundred $$ in it between Teric on sale and Tern at retail.

Looking at the comparison table above, the Tern TX is looking like a good contender, and from what I understand the battery is different to the Teric. I guess is there any sense that the latest production runs of the Teric have resolved the battery discharge issues? I think I'm leaning towards watch style vs something like the Perdix 2, just as I prefer to keep my computer on between dives/post dive tracking surface intervals, but would only wear it during dive weekends/trips, as I have other watches for the real world.

For context, I'll be looking to do a few local shore/boat dives every month or 2, with some (4-6) holiday dives a year, plus an extended (7-10 day) liveaboard every couple of years. Moving into tec diving isn't on my radar for the next ~5 years, but I am tec-curious. I am consicous of the battery issues and managing discharge between dive trips.
