I have one, It shoots great. No failures to feed or fire so far. Pretty accurate once you learn to handle it steady during the trigger pull.
Not sure about Conversion kits, but the price of the conversion kit will be close to the the price of the gun
I did change the recoil guide rod and spring on mine. The stock one is plastic, weak material, I installed solid stainless steel one from an USA seller. Flat shipping 10$ to canada, no additional fees.
I got the rod and spring from this place :

DA pull is the best I have tried so far, smooth and not heavy. It is just long.
It is a great DAO pistol in my view. Very reliable so far, easy to disasemble and clean.
