On the point of a router, if the rotation is so sloppy that it cannot be accurate then it will not only shake itself to bits it will be dangerous. The main input as to accuracy is the quality of the bit [1] and how sharp it is. Issues of fine height adjusters and micro adjustable fences are more time savers than true accuracy aids. The argument for buying a cheap router is the necessity of getting a job done within a budget. Which is why my first and second routers were Power Devils, I sunk my money into reasonably decent bits (Trend largely). The first one still runs, it has been permanently in my table since I bought the second one. When the second one died (blown upper bearings which wrecked the bushes etc) I had enough to get a T5.
If I had an urgent need to run a half inch bit (panel raising is probably the most likely use), I might be tempted by such a router, provided I could fit it on my table. Especially since decent 1/2" panel raising bits aren't cheap ;-)
