I have a Sihuadon D-808 for sale. I bought it a few years ago. I used it occasionally but I recently pulled it out and found that it does not turn on. I replaced the main capacitor but that did not seem to help.
I'm selling it for $10 in case you are better at diagnosing electronics issues than I am!
The body is physically in immaculate shape, I've always kept it in the original carrying pouch. Included is the carrying pouch. I am not supplying an 18650 battery with it, but that's the size it takes.
