Never had an interest in one. I had one SIG that was DAO, but converted it over to DA/SA as quickly as I could. I'm no fan of DAO. And the MUCH better half has incredibly little hand strength. She can't effectively manage many DAO trigger pulls. So any gun I buy, I want her to be able to operate. So in essence, DAO is a deal killer for me. Had they made a DA/SA version, I might have taken a serious look. It is an interesting concept, but just not for me.
