So the other week the big-honking power adapter for my Sega CD was on the fritz. I looked on ebay and replacement adapters were reasonable enough. But they I stumbled upon the Trident!
This was basically the answer to my prayers. Instead of three adapters for your 32X/Genesis/SegaCD combo, you have one plug that splits into three wires! And it works! Highly recommended!
I've been using adapters from RetroGameCave for years, including the Trio M2 that is a single adapter solution for Model 2 Genesis/32X/Sega CD (also have the Trio M1, for model 1 Sega CD)
