Curious....they don't list brands.

Might be because almost all of it is made by a couple of manufacturers overseas,just re-boxed under different brand names. You're getting the same panel, only the names on the boxes and the prices differ.

Yearone seems to be more expensive that others.

I'd have to receommend you should check with BelAir Bob, i've purchased several pieces from him. Plus he a sponsor of the site.
