You may want to check out Bearings Canada. I picked up Nachi angular contact bearings fro my mill for less than expected.Regarding the bearing replacement - McMaster has good options for all besides the two angular contact bearings at the bottom of the spindle.

The angular contact bearings are 7207b. I removed the old ones which are Made in Japan NSK brand and look/feel to be in good condition. Mcmaster lists 7207 for $86 each. https://www.mcmaster.com/6680K18/
This is my first hobby machine and I do not want to spend a huge amount on bearings. I do realize their importance, but everything is a balance. I want to get to know the machine, make some parts - which I never have - and see how I feel from there.
The ones I linked to are not Nachi, but they do have several varieties of Nachi 7207.I see well priced Nachi bearings on ebay then questioned if they may be counterfit. The price on Bearings Canada suggests maybe not - but I don't see anywhere on the link posted that those are in fact made in japan.

These bearings are non-separable. Since the balls are inserted utilizing counter-bore construction, a larger number of balls can be installed than in the case of Deep-groove ball bearings. Standard cage materials may be pressed steel, high-strength brass, or synthetic resin.www.ebay.com
