I've got the DeWalt 2hp plunge router (dw621) and if I had it to do again, I'd purchase a different one. This may be due to my application. I needed an all purpose router that I could use in many different ways: freehand/guide bearing type work, table mounted, etc.
My main gripe is with the switch. Yes, I've heard many say "it takes some getting used to," buy my disappointment goes deeper than that. Whenever I've got it mounted in a table, I have to put a clamp on the switch to keep it ON. The lock mechanism that they have for this purpose...well...lets just say that their engineers could use some refresher courses. It vibrates itself OFF almost immediately.
I also feel that that the base is too small and ackwardly shaped. It always feels very unstable when trying to run along the edge of something with a guide bearing. It really needs one of those offset acrylic/plexi bases with the handle to use as an "outrigger".
Trying to run it along a fence is also difficult because the shape of the base is goofy. Flat on opposite sides and rounded on the other 2 sides.
Other than that, it's fine. Plenty of power, smooth plunge (once you figure out that the springs to return the bit to the retracted position are about 10X stronger than they need to be and it'll just about rip the whole tool out of your hands when it springs back), good speed adjustment, 3 depth stops, easy to change bits.
Just my $0.02...hope it helps.
