Any first hand info of these doubles guys? Saw one this morning (sweet little 20 ga.) and it seemed a good first for my son... I have done some google-fu but very little useful info out there.

It's become clear that these are very new to the market. Any thoughts, as time passes, will be appreciated.

I recently picked one up at a local shop that had a $499 price tag. Looked decent enough. For the price difference though, I would personally go with a Yildiz at Academy. That is not a knock on the Cavalry, the local Academy has the Yildiz brand for $429. They have been around long enough to know it is a decent gun. If you are not near an Academy, that might change things.
