Based on my experience with the SDS2000X HD, just under a year....
No, if there are really "bad" bugs, they are usually fixed quickly.
The "problem" with the SDS2000X HD was that it is based on software that is already very mature, so there was no update so quickly.
The 3000X HD/1000X HD will be no different.

Also an SDS3034X HD ? Very nice, then I'm not alone...
