I hear nothing but great things about the Porter-Cable 690 router. It seems to be one of the most popular with the guys doing major wood cutting with CNC machines. Below is a link at Amazon for $139.99, the best price I could find locally was $179.99.

Oh, and it's reasonably quiet too when you employ a speed control and reduce the speed to better match your feed rates that you'll be using with CNC. These things run way too fast unless you are cutting at high speed.
