I have the big Hitachi M12V2, that stays in the table. Also the discontinued red top Craftsman that was a clone of the Bosch 1617 with fixed and plunge bases. The fixed base has above table height adjustment, but I never used it in a table(in fact I've never used that base at all). My old Bosch 1613 has the same feel as the Craftsman and the(plunge) sub bases interchange. I make my own subs and usually keep one for PC guides on the Bosch. And one for the larger guides on the Cman. I also have a Bosch Colt that I would'nt want to be without. I'm sure I need a few more, but I'm very happy with the ones I have. I used to have a PC 690. It was my first "real" router. I loved that router, but at the time, needed to sell it to purchase a plunge router. Thinking back know, the only thing the 690 can do that the Colt wont, is take 1/2" bits. The router I upgraded to was the Hitachi KM12SC(no longer made, I think) with fixed and plunge bases. It was my first plunger, and worked well. But when I got my hands on a Bosch plunge, the action of the Hitachi plunge became very disappointing. So it went out by way of Craigslist. The action of my big Hitachi may be no better, I don't know. I took it out of the box, removed the springs, and stuck it in the table. That's where it stays, and it works very well for that.
