D&M Flooring experiences?

Hello,

We are considering floors from D&M Flooring suggested by a local installer (here in California). I was not able to find much on this manufacturer and curious if anyone here has any experience with their product. We are specially looking at this oak flooring:

There is no shortage of praise on the internet for manufacturers like Mirage or Lauzon, but are their products really so superior that there are no comparable competitors? How should one compare product lines when there are so many "European white oak with UV cured urethane" etc.

Thanks for any info!
