i am awaiting my black dragun in the mail as we speak. so i haven't had one for a year but i have done a ton of reading about them. they haven't been out that long. most guys with them have only had them for a short period.
they are spyder based so the reliability is there out of the box. some people say they seem tighter and more solid than a spyder. the only complaints i've heard about them is they sometimes don't recock after shooting real fast (but it can be solced with a new bolt), the bolt tears up the chamber (again new bolt) and they have a wierd bolt pattern for bottom lines and drop frowards. if you get one that isn't for a black dragun you have to buy an adapter plate.
but who can beat 13 bps for under two hundred (or in the case of the LCD--multi modes for under three).
