I had my RC car stolen many many years ago...
I still mostly use my PD20 and Q123 most, but that's for work and I don't need more lumens for my purposes. More runtime could help, but I still get by easily. At night I still use another Q123 or my Nitecore IFE2 somewhere between 2 and 60 lumens. I'll whip out the big guns for the occasional grin or if I hear a suspect sound but that's mostly it. Then again, I haven't been camping in a while.
I kinda translated my flashlight passion into electronic cigarettes:
I did that one to play a joke on the ladie's forum on Electronic Cigarette Forums, but that thing costs as much as a Surefire and is of equal quality for an e-cig and still does not have the highest power of all e-cigs. At least it's a hobby that can actually save money if you don't indulge like you're buying flashlights - many people do and have as impressive collections as you see on here. I got my lesson from buying flashlights though, and am aiming for 3 great quality mods and that's it. Why 3? because 2=1=none, of course! Fun fact: the first electronic cigarette was actually made with a flashlight from which the emitter was replaced with a coil... It still is very similar (variable output, PWM, changeable heads -maybe one day with a flashlight head-, almost 100% legoability throughout brands, some have LED's and most basic terms come from the flashlight world.) In other words, the newest stuff is based on flashlights, but for a different application.
I'm still planning to save enough money to buy a Lux-RC and a couple more MBI's at some point.
To further answer your question:
The MBI torpedo made it through X version (experimental) with a batch of about 100 sold and the final revision is coming closer and closer after 3 years into development.
