I personally really like my Bosch colt router, but on the MPCNC forums a lot of folks are swearing by the DW611, or ideally a 220V watercooled spindle. My understanding is the colt used to have very low runout, but allegedly QC has declined and runout on colt collets that can sometimes be too much for finer work. I bought my colt for work about 2yrs before building a cnc, so it was a natural fit when I was putting together parts for my cnc. It has served that purpose well IMHO... cut some small alum parts with fine details, cut pcb's all the time, and even did good in the 'mpcnc drag race' event (I think fastest of the non-watercooled spindles actually). That said, if I was refitting a new spindle on mine today, I'd be looking at watercooled (lots of great info on the mpcnc forums about this).

IMHO one of the major advantages of the Bosch is it's RPM feedback speed control. It's capable of lower RPM than most small routers available, and it holds RPM fairly solid while cutting. As you may have learned with your rotozip (I also have one of those for work ;)), the speed you want your bit to turn is usually a low slower than what most small routers can do. Also, the rotozip like most cheaper routers, does not have RPM feedback, so as soon as the bit starts cutting, RPM drops significantly. That gives less control over the process, ultimately leading to lower quality parts. There have been lots of discussions about adding RPM control to the DW611, which may be of interest to you... but in the end the watercooled 220V spindle will be the one that allows you to make the most out of an mpcnc.
