Flash directors can be made as described, they work.
I have a used Sunpak DX-8R which I bought here on the Marketplace. I had to track down the Pentax module separately, but it was not expensive. I use the flash in manual mode, having learned the proper amount of light to add based on conditions. It's not as hard as it sounds. When shooting 1/160sec, f16, ISO 100 at 100mm I use 1/4 to 1/8 flash power. Add the 1.4X teleconverter and that goes up to 1/2 flash power.
I think the Sunpak is likely the least expensive strobe ring flash option.
But yes, you will get a ring-shaped reflection in insect eyes.
