pp5858, I recently bought some of these cheap AA/14500 lights.
This one was influenced by mizou51 review. It has a front LED (High-Low) and a COB side light (High-“Blinky). Works well with AA (alkaline and Ni-MH) and 14500 batteries.

From the same seller I bought this zoomie 1 mode flashlight. The original tint was the “bluest” I’ve ever seen so I modded it and now it is a usable light with both types of batteries (although I use it mainly with 14500).

Aside from those mentioned above in The Miller’s thread, the “cheap but decent” AA/14500 lights I’ve seen are a bit more expensive (5-8€) and have more modes, like Thorfire TG06/TG06S; Sofirn SF10 /SF12/ SP10A /SF14; Ultrafire C3 (1 mode only); Trustfire S-A2; or some “SecuryIng” flashlights (in AliExpress).
