well i see many people giving credit for Milwaukee and Makita, but not that many for Porter Cable. So i will through in my two cents.
At the beginning of this past summer, i started my own tool collection, (my dad has a decent radial arm saw so i have that covered) so i then thought of what i could use, so i started looking and came to the conclusion that i needed a nice router.
So i started looking around and nothing compared to Porter Cable. For their build and simplicity, there's no fancy decretive plastic parts. It took both 1/2 inch and 1/4 inch bits, had more then enough power, and is a leading standard in the industry, almost every accessory is compatible with it. So i got the 690, its the 1 3/4 Hp fixed base router. The reason why i wanted the router over any other tool is that i am planing on building quite a few speakers in my time. I have already built a Subwoofer and a pair of 10" two way monitors and this is the most versatile tool that i have ever used. Along with the router, i also got a really really nice router table from Rockler.com, its the Master R lift table, basically i don't have to take the motor out to change bits, and i can crank any hight i want, which is really handy when you are changing from a 1/2 round over to a trim bit.
I have used my router table combo so much on my last speakers that its not funny. I have a circle jig that i cut out all the driver holes, and port for, I used a pattern bit to cut out the terminal cup hole. I used the table my biscuit bit to biscuit join the front and back baffles. I also used a lock miter bit on the top and bottom edges. Needless to say i have put some hours on my PC and to tell you the truth it will take it for many more years and speakers to come.
here are some links to my table, and my monitors
