DIY Bearing availability

I'm getting ready to start another TT project and not quite sure I want to machine one or have one made.

What is out there now? I didn't see bearings listed on the Teres site but will give Chris a call to see if he still sells them. Any other options?
Or this one, with magnetic levitation. I have purchased from this seller before with good results. He has a number of turntable parts, some odd, some interesting.
That's the same seller. Unfortunately, that bearing is only for an up to 3k platter. I still haven't heard back from him about the other bearing.
He has another bearing he sells with his POM platter. Scroll down some and you will see it.
