I have the Bosch Colt, with all the add ons and like it. But I think the 611 is easily its equal and in a few ways, better, in particular the clear plastic base. I bought the Colt with only the fixed base and wound up paying a lot more for the plunge base and a 2 handled wide base for better control. A small router is so much nicer to use freehand than the 1617 when that extra power isn't needed, such as hinge mortises and small roundovers cut freehand. I don't think you can go wrong with either machine.
The more I do, the less I accomplish.
