I've used "lazy susan" bearings for my homemade dob base.
I had the first one you listed:

And it work fine(smooth motions) for a few years until one or two ball bearings got out. I've since went with a better quality 12.75 "Lazy Susan $22.50

Aluminum Lazy Susan Bearings

This one feels a little smoother and better built than the $10 one. No issues with the weathervane effect, but my 12.5" sonotube dob is heavier than the Intellescope metal tube and like Buck said, if you want to add resistance, a piece of carpet or felt will work fine.
