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?
Nice ready-made track for an idler wheel on the underside of that eBay offering, but it would have to be one powerful motor to move that sucker. Does look to be beautifully made.
Why not buy the platter upgrade for the VPI series turntable? It includes the bearing and the platter that is used on the classic. $800 from music direct. Can't beat the price can you? Or if you can please let me know!
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.
