I found a Weishi No. 1900 on eBay for $5.30 (free s/h). I checked the store, looks like an importer of general Chinese electronics. Clicked back and forth a few times to see if it refreshed and disappeared. Read/reread/re-reread the listing to see if it was just a part for the 1900. I checked that the price was USD.
Ah, what the hell, I’ll order it, they’ll see the mistake and cancel it. Then I got a shipping notice.
It got here today. Brand new…
