I would add to this thread that I ordered a bunch of stuff from Chunger a couple of weeks ago and also haven't heard anything since... But everyone's notes here that he is reliable and always comes through makes me not worry about it. I also run a small business myself and although I do try very hard to remain in contact with everyone who mails me things for repairs or adjustments and orders stuff from my shop, it is very much its own full-time job to stay in touch with everybody all the time. So I get it. Life would be easier if you just didn't reply, lol. I routinely can't get to things for sometimes 3 to 6 weeks until after I receive them for work, too, so I'm imagining he's just a busy guy and get a lot of orders and maybe has a family or a life outside of all this too. As long as the stuff shows up eventually, it's all good in my book.
I actually thought about stocking some mic bodies myself as a side business. Maybe I will. I think they at Shuai Yin said minimum order is 50 pieces? That would be expensive though... $5~6k per model, probably. Plus, some of theirs don't fit all of the boards out there, like Poctop's PCB's for the M49 doesn't fit the M49 body I bought from them for example. It will fit, but the internal frame is too narrow so it'll have to be improvised more. I don't know where Chunger's comes from that fits Poctop's boards. I think this would need to be coordinated with whoever is the most popular DIY PCB maker people generally want to use for their boards. And it would have to be someone who had enough money to invest in it as a business. For me I probably couldn't risk that much money unless I knew I had confirmed pre-orders for units that would at least help me break even on the initial investment. It's something I would want to do though.
