As usual, I do a bunch of digging and end up going in a different direction.
I ordered this one...which seems to have a lot of the features of those above at a lower price point with some added benefits.https://masscaproducts.com/
1. Aluminum body rather than plastic
2. USA made-small family run business
3. standard hole sizes-so if the drill bit is crap, i can replace with a kreg bit
It does not have the auto-adjusting depth feature of the Armor unit, but has a built in step height knob for depth setting which looks easy to use.
