I was getting close to pulling the trigger on a set of these M1 boost centerlock and it says plenty are in stock but they can't be shipped to the United States.  I found other AlixExpress stores that will ship and I found them on Walmart but I'd prefer to get straight from Ztto.  I sent them a message but time difference means they won't reply.  Trying to figure out if I build myself or order full wheels from BTLOS before their free shipping ends.  Has anyone in the United States been able to order directly from Ztto official store on aliexpress?

I just received a set from ZTTO Bike store. I am not sure if that is their official store or not.  I guess I assume it was.

Where is the creak coming from?  I also have this frame and my lower shock mount boot was slightly under sized by .08mm and it was creating play in the linkage.  I ended up making my own out of some bar stock and it took care of the issue. 

I am in the same boat as you in looking for a full suspension + bike.  couple things i would add to your list. 

FS27 -
- it does not use a trunnion shock it is just upside down.  any regular shock that is 165x38 will fit. 

Dengfu-
- the Geo is the same as the M06 frame.  all they have done is create a boost spaced rear end.  i emailed them about this frame as to me it seems like the best option.

-i think a lot will come down to the geo.  all the designs have been proven by some name brand manufacturer so i would not worry about that.  like the flex stays of the FS27 and FM006. 
-the 165x38 shock is a pretty common XC bike shock size so i would not really count that as a con unless the travel that it provides is not what you are looking for and then that pretty much should rule out that frame anyways.   
-you have both XC and AM head angles as pros, that tells me you may want to look at what you want the bike to do.  those are kind of mutually exclusive riding segments.  find out what you do more of and go with that frame. 
-the P9 is listed as OEM old so not sure if Joe Public can buy this.  something to look into. 


just my thought

cheers

Sorry for resurrecting an old thread.  i just spoke with Melody last night about this frame.  the front triangle is the same as the M06, it is just the rear that is different.  i wanted to know if it would work with a regular 29er and she said yes.  the geo is also the same just with boost spacing at the back.

I know this is old but i am pretty sure the frames they use are the same as the DengFu FM190.  they geo is identical and the chart even looks identical.  i looked at the Lamere but i could get an entire bike by going with the FM190 over the Lamere with the same geo numbers.
