I have bought Woodcraft and MCLS bits, both of which seem fine. Like Ethan said, I try to buy most of my bits with the 1/2” shank, which provides a more stable bit.
One of the woodworking magazines had an article recently on router bits. They tested both expensive and inexpensive router bits. They noted a few items to look for on the more expensive bits. They concluded the inexpensive bits do have their place. While they may keep sharp as long as the other bits, the use you get from them may justify the cost. If you use a bit just a few times, the inexpensive one may be the way to go. If it is a constant use, the expensive will win out.
