You will always get what you pay for.
The more expensive bits have three things going for them:
1. A higher and thicker grade of crbide, resulting in a better cutter
2. Better bearings. I had a Grizzly bit fly apart on me years ago. I understand
they are better now.
3. A properly balanced bit. Balance is important for a better cut and the life
of your router.
The PC router is a great machine. It's so called lower horsepower rating does
preclude you from the largest panel cutting bits, the ones that should scare
the daylights out of anyone; I use it for middle size panel cutters, with small
cuts, and the results were excellent.
I've had excellent results from Freud, Amana, Eagle, CMT, I know Jesada is
excellent. Eagle is a great compromise. They are reasonably priced, very high
quality, and their service is excellent. I go tho them first in fact. Amanas
have been the best I've found.
