I have a Bosch Colt PR20 palm rounter. I got one when the first one
hit the stores because I really liked the design. Still do. However,
I find that there is more vibration than I would like to see in a
router of this quality level. I mentioned this in a review of it
several months ago. It has much more vibration than my DeWalt trim
router, or for that matter, any of my routers. Maybe it is normal, but
I have not been able to compare it to other Colts to see if mine is an
exception or typical. The reason I am bringing it up here is that I
put a little LED light that Dremel is selling on it and the vibration
tends to make the light wink or flash (I assume due to the battery
contacts being vibrated).

Has anyone got experience with comparing the colt vibration with other
trim routers and can tell me their impressions?
