Just for a recap - the original question:

Bitmain did respond to email overnight. No chips to sell at the moment, but they may let me know if anything comes up.

A3 ASIC and A4 ASIC design already. Both in 14nm and already taped out with over 60% power saving over the 28nm generation. Anyone interested in those are free to contact us.

Is it still possible to source chips nowadays? Updates from Googling:
Avalon: https://ehash.com/product/a3222-20pcs/ doesn't work. Seems like they only sell actual miners.
Bitmain Tech: Seems like they only sell actual miners.
InnoSilicon: Looks like they might. Has anyone obtained new or old gen chips from them?
SFARD: Read the entire 82 pg drama filled thread. Seemed promising but a dead end?
Spondoolies: These guys have shut up shop. http://www.spondoolies-tech.com/blogs/news

I'm a hardware/software enthusiast but it seems like a mission and a half to trudge down this path.
