I have owned my Makita M12 /3.5hp plunge router for 7 or more years, and like its power and ease of plunge height adjustment. Mine is mounted in a Veritas (Lee Valley) steel surface router table. It has a home-made crank for height adjustment, and while only a single-speed model, works well through a plug-in speed controller. The only real complaint I have is that the bit is difficult to remove after use. The nut is not over-tightened, and the collet and inside shaft are rust-free, but sometimes it requires loosening the nut entirely then tapping the bit and collet with a piece of hardwood and a mallet. I've also tried using a bronze-phosphor brush to clean inside the shaft; used 800 or 1000 grit wet and dry paper to polish; ensured that there are no burs on the bit shank; even put a drop of light oil on the bit shank prior to insertion. Yet the same damned problem remains. Any solutions out there? (And no, I'm not going to replace the router).
