Well not the "Pro E4" ones but ZRACE have them as just levers... They show them without the thumb screw reach adjusters but I queried them and they can swap them to the ones with.

Yep!
I ended up ditching my Shim-e4 experiment and reinstated them to stock e4 setup to put on my hardtail. The hardtail has been my bike of choice for the last few months and the brakes have been in use around 2 times a week since maybe January.
They still work well. We've had mostly dusty conditions all summer, but the last week has been muddy and...they still stop me. I'm a midget though, so take that with a pinch of salt.
Avoid them if you don't like on/off feeling brakes.
For the price I rate them.

Looks like they have an updated model with different clamp design and a banjo fitting for the caliper.
Tempted to buy one for my DJ bike, but I can't bring myself to run a RH rear set up.

That's what I was thinking.
Then just do a lever bleed with a shimano cup with one of these adapters.
EDIT: FWIW, My Zrace levers (similar the the pro e4s) have been going strong and mated to some sram DB8 calipers has netted some quick powerful brakes.

Brakes should not be "quick".
Stirring aside, I was quite impressed with your Z-race DB8 setup. Had some stopping powerz!

At least one part of my bike should be quick.Brakes should not be "quick".

It's definitely not the pilot/rider/driver/passenger...

I never had an issue with the clamps and simply popped the clamp ring onto my bars without the need to remove anything. I was lucky too I swapped the hoses over (very carefully so no air or as little as possible would get in) and had good braking from the get go.
They replaced a set of Juin Tech DB1 brakes (dual piston) which cost twice as much. The IIIPro E4 weigh about the same and stop better. They look a lot easier to bleed. The Juin Tech DB1 are a complete PITA even the mech I take my bikes to occasionally, had trouble - that's why I took them to him
I just bought another set, they changed the name to IV4 (?) there are some slight differences in the hose connections. I bought them to replace a set of Shimano Deore where the rear always seems to get air in the line and constantly need bleeding or a 100 pumps before it will brake, then you have to keep pumping them while you're riding to keep them "stop ready"

My latest order of these IIIPro E4s in their latest iteration called the IIPro C5X4 with the "quick release oil pipe" design. See
https://www.aliexpress.com/item/100...o.order_list.order_list_main.4.60f31802A9s7PE .
It really does work quite well. There is no olive, but there's also no instructions! So I had to carefully try to figure out how it worked. That little black screw takes a 2mm allen key. It holds the connector in place, quite solidly. Even if it is just slightly over the edge, that connector won't budge. The screw has to be fully withdrawn from the "connection port" which happly doesn't mean you have to completely remove it from the lever assembly. See pictures #1 and #2. #3 shows you get a couple spare connectors - which you shouldn't really need.
The rear caliper and hose, as usual come disconnected from the lever assembly for easier internal threading. You can see in #4 the end of the hose has a plastic stopper inserted into the connecter to seal in the oil. I had to swap the levers and it was even easier with these quick connectors. Again I also managed to do it without losing any oil, nor I think letting in any air. They are working just fine with no spongyness.
One thing I found with twist grips is the lever adjustment knob will come into contact with shifter body and so you have to set them inboard a bit and I couldn't angle the levers down to 45deg like usual, more llike 25-30, still comfortable enough. These older style SRAM 9spd grip shift are worse than the newer style grip shifters.
For sale one pair of Shimano Deore brakes! These IIIPro C5X4 shit all over them.
