Bill, I agree with the recommendation of the DeWalt 621. I have the Elu version of this, the Elu MOF 97. This can be seen in the middle, below, to show its size relative to the full size Elu 177e and the baby Elu MOF 96 ...
The DeWalt 621 is a 1/2" and 1/4" model (my Elu MOF97 is only 1/4"). It has excellent dust control and, importantly for your needs, a micro depth adjuster as well as a coarse depth stop.
Here are the parts ...
I have been using the two larger routers for over 20 years. They are balanced and powerful. If I was looking for a new router, I'd go for the DW 621 as well. Far better value than the equivalent Festool.
