Bosch’s Colt router has been a hugely popular model, and for a long time. I find myself easily trusting that Bosch designed the GKF125CE to be a worthwhile upgrade. At the least, it’s more powerful. At best, it’s more powerful and has several years of ergonomics research contributing to superior user-friendliness.
The previous/current generation model, PR20EVS, is rated at 1 hp and 5.6A, compared to the new one’s 1.25 hp and 7.0A motor rating. It’s less expensive though, at $99 for the router compared to the new one’s $129 price. There’s also an established accessories ecosystem supporting it. A plunge base for the GKF125CE will be out soon, and I anticipate that it won’t be long before its accessory lineup matches that of the PR20EVS.
