The most recent review of trim routers, in the August 2008 issue of Fine Woodworking, joins with five earlier comparison tests in giving top ranking to the Bosch Colt PR20EVSK (*Est. $120) trim router, with electronically controlled variable speed. Reviews praise the 1.0-hp soft-start motor, self-releasing collets and two-stage depth adjustment (fast coarse adjustment, plus fine adjustment). The single-speed Bosch Colt PR10E (*Est. $90) has all the same features except variable speed. Reviews note that a single high speed is usually all that's needed for a trim router. However, the difference in price is relatively small. Both Bosch Colt routers are fairly quiet as well as comfortable for both right- and left-handed users.
The Ridgid R2400 earns some praise in a single-product review at Woodworker's Journal, but doesn't make the cut in any of the big comparison tests. Like other Ridgid power tools, it carries a lifetime warranty once registered, but the Fine Woodworking review notes that changing bits "was a hassle" and the baseplate made the router wobble. If you need to compromise for budget reasons, reviews suggest the Grizzly H7790 (*Est. $45) or the Chicago Electric 44914 (*est. $25).
