You're going to like the modded shocker, and d40a... I like mine a lot. Part of the reason I'm not getting a TK75vn killer throw version, is I don't see how it can compete with the modded shocker I already have.
About the Eye40vn, I think it's a very nice light. It does get got on turbo pretty fast, but still very usable for scanning, and perfectly usable at the lowest levels. It's just not a light that you grab if your goal is to find the toilet without tripping over anything in the middle of the night.
The only issue I do have with it, is that there is no good way to lock it out. You have to almost remove the battery case to lock out, and even then it's not a 100% guarantee. I doubt the standby current is high enough for that to become an issue.
The TK75 is still my all time favorite of the big lights... so far nothing beats it. The TK76 is interesting, but those two empty holes on it bother me too much.
I suspect you're going to be very happy with the MX24L3... I love playing with the light using the color filters.
