It has been my experience that when it comes to router bits quality rules the day every time. Good quality bits, such as Whiteside, CMT, Freud to name just a few, will usually be priced fairly close to each other. Poorer quality bits will be price all over the place but generally will be much less expensive. Results are the key here and I've yet to find a lesser quality router bit that can produce the same high grade results as the name brand can.
Life is like a roll of toilet paper.
The closer it gets to the end, the faster it goes.
