Chinese track frame group buy

Ok, after much back-and-forth and diving down the rabbit hole I am speaking to Top Fire about their track frame and wheels. Decision has been driven by:

1. They seem to be a genuine OEM. I've spoken to 4 different companies who've each claimed to be the OEM for some of the more popular track frames which is a bit concerning
   
2. Their track frame is exactly what I'm looking for (https://www.top-fire.com/aero-carbon-track-bike-frame-for-bsa-system_p13.html, I think Viviani won a WC on it in 2021 and it's very similar to the Electron Pro geom)
   
3. They have a good selection of wheels and other bits if people want to order some to go with.
   
   

Still remains to be seen whether there are any cost savings to be had vs. just buying on AE as mentioned above but @Rjfreeman, @eespark, @Charger, @Leshaches if you're interested have a look around the site and let me know what you'd be ordering and then I can move towards getting a quote.
