I don't know that the a2824 is available from the noob factory in a sub is it? I can't answer that. I know for sure the a2836 is. I would definitely go for the asian 2836, or if available the a2824. The 3135 may look a lot like the gen 3135, but really why does that matter? it's inside of a closed caseback that no one will ever see. Parts are a challenge sometimes to get too. I just personally don't see the point in paying a lot more for the 3135 when the 2836 functions exactly the same for a cheaper price. but everyone has their own thing. but go to the movement's section and do some reading about the 3135. you will read post after post of it just not being quite the proven reliable movement yet. sometimes they work great and people don't have any issues at all with them, but if there is an issue it might be a little tough to get it repaired. But go there and do some reading theres a lot of good posts about the 3135. There's a couple different 3135's also. From what I've read the yuki 3135 is a good movement and seems to be reliable so far, but you don't get that in a noob.
