Wow, the Woodpecker model everyone likes is nearly seven hundred bucks. I got my JessEm Mast-R-Lift II for about half that by watching for price drops. It's $349 today on Amazon with Prime shipping, a relative low point for this lift. It's time to jump.
I really like the JessEm; it is a precision tool. But I notice that others have expressed a preference for Incra's magnetic inserts to the red phenolic ones on the JessEm. Other than that and the color, the JessEm and the Incra Mast-R-Lift IIs are the same. Rockler sells the Incra for $399; it fits their tables. But you're making your own, so you're not limited to one plate size.
Mine enables me to adjust the bit height to within 0.001". That's hard to beat at twice the price.
You say you want a minimum of adjustment tools. For the JessEm you need the crank, a proprietary spanner to remove the inserts, and the same collet wrenches that every router needs to change the bit. Very simple. My crank and spanner live on 3/8" rare earth magnets on the legs of my extension table, right where I need them.
You asked about dust. I screwed together a simple box out of 1/4" MDF, with 1x1 corner braces, and screwed the box onto the underside of the table extension. So easy. Here is a view of it upside down; you can see the little slider door I put in for the power cord. There's a larger slider door on the other side I can fit my hand through, to adjust the speed on the PC 7518 (a recently extinct species). That's a full 4" dust port. I also sometimes use a 2-1/2" port on the fence, depending on the cut. I never have dust in the room from the router table.

Note that if you make your own table extension, as I did, you would be wise, I think, to buy the
MDF template for routing the recess. Mine was 3/4" thick. Some you find are 1/4" thick. I'd rather have the 3/4", and it might even be less expensive than the 1/4".

It's something you use exactly once, but I wouldn't want to do the job without it. Well, twice maybe: I did a dry run in Baltic Birch just to see where the failure causes might be. When I was done with the template I found a home for it in my local woodworking club and got him to promise to pay it forward to another member when he was finished with it.
One other tip: with the way the height adjustment screws work, you run the risk of digging into your table if you use wood (and don't we all?). So I recommend getting a 1/16"-thick
steel mounting plate to rest the heavy lift on. That's something you use every day for the life of the lift. My lift plus 3-1/4 HP router assembly weighs a total about about 28 pounds. Very solid on the steel rim. Here's where I got mine:

Size of router: I don't know about the Bosch 1611 plunge router (I couldn't find it anywhere), but the Mast-R-Lift II fits the Bosch 1617 and 1618. Does that help? JessEm makes a big thing about fitting virtually every router motor made, but there is no need for a plunge mechanism in a router lift.
Now, about customer service: With the JessEm, I messed up the mechanism through my own error: I overtightened something and it broke. I called JessEm and spoke with a knowledgeable live person who sent me the replacement part I had broken, free of charge. I don't know about you, but that seals the deal for me. Plus: 0.001" fine adjustment! I love this thing.
Good luck.
