Hello folks!
I was searching around on aliexpress today and found this: https://www.aliexpress.com/item/New-...c339e107&tpp=1
The 450 looks particularly promising, as it may even use a single-mode diode. That would be quite a bargain at $20. Also, the beam of the 450 appears to be clearly visible with no fog.
It is likely that these pens can accept standard 12mm modules, which is nice.
I have asked the seller for more details.
Edit: Looks like I found another source. I will ask for more info.
