Bearings

Bearings and Bearing Mounts.

What are the best? Pros, Cons.

My Miyata has what I think are called press in bearing mounts and I was having a
problem with one of them coming loose. (Thanks, to all those on the list who
gave me help with this problem.)

Since that time I have decided to try my hand at assembling a my own cycle. (and
have been shocked how expensive it is to custom build a wheel) Bearing appear to
be a critical component. So what are the best?
