I started with a Bosch 1617 with above table adjustment (once you modify the Rockler plate to allow for it) and needed a second router to be able to do some hand routing. Wound up buying the PC 3 1/2 hp, mounted it on a rockler plate, seem to flex the plate and changing the bit required pulling it out of the table.
I found the bench dog lift on sale, so I didn't have to mortgage my first born, and put the PC in to. will never go back, but I could have bought another tool with the money. These are toolls my grandkids will be using, if they can pry them from my cold dead hands. Tons of good lifts. Try to find someone with your router, then ask them about lifts, so you can gain some insight before you make your final decisions.
My Bosch with built in adjust was "good enough" for everything I do, but I always measyre, twice and then use "shorts" to test the cut, set up, depth etc, to ensure I got what I think I got.
By the way, routing is like an adictive hobby. I now have 5 routers, tons of bits, three of them a PC 690 with two fixed, one plunge abd an plastic box of bit, bushings etc for 60.00, two craftsmen, one low end, (probably less than $100.00 new) and one craftsman professional with case and accesories for 40.00. Now I don't have to change bit back and forth so much.
