I am planning to install engineered wood floors (probably red oak,
natural) over a concrete subfloor in my condo. They will be glued
down. Many of the brands I have seen have a thin wear layer of wood
or look cheap. Have identified Mercier, Mirage, and Lauzon as brands
I am considering.

Does anyone have recommendations on a quality manufacturer with a
product that looks like "real" 3/4 in hardwood? Any experience with
the above mentioned brands?

Thanks.
