Chinese track frame group buy

Good q, few things behind this:

1. I'd really like to get hold of one of the integrated stem frames which from what I can tell are longer sold on ae as someone (still trying to figure out who) has bought the moulds.
   
2. I've seen the group buy work well for some other things and I'd like to see what kind of discount we can negotiate.
   
3. Hoping that going direct to manufacturer should be better from a QC perspective.
