It seems we are both on the same quest for a good dual 123 light for a Brad conversion. I'm also waiting for a reply to your post, as I don't have such a light yet. There's also the TACM III which fits this bill, but there isn't too much information about it. YeeDude has one, and I've read some of his posts on Bladeforums, and seen their website. Brock reviewed it but didn't like it. I'm not sure why. The only other option is an Underwater Kinetics plastic light, but then you buy one, followed by an E2, and then you've essentially spent, well ~$100 for an E2. Like yourself, I figure a Scorpion or E2 is the best route, unless I can get more positive feedback and details on the TACM III.
