Maybe a bit over the OP's price point, but why not try to find a LF2xt. Nothing else compares.
It would be too old for such complex electronics to be dependable used. Yours may still be fine but seller's may not be. It's also a little complicated for my taste.
Hey recDNA - may I ask in your 2+ year search if you have found a light that fits your needs?
I think the LF2XT would still be your best bet. It has a simple UI mode that is not too complicated. Also - I find your remark on dependability to be completely unfounded and based on what? Because you think the electronics are too complicated? Just so you are aware the electronics on this driver are no more complicated than on your typical $5 AMC1735 based chinese driver for a P60 drop-in. It's all in the programming of the mCPU. I have personally owned over 20 of these LF2XT lights and probably had another 10-15 pass through my hands doing mods. In all that time I've only had one catastrophic failure and that one was entirely my fault when modding.
Personally, and completely my opinion, but if you have been looking for a light for 2+ years and dismissing every option thrown your way then I have a question and a statement for you:
Question - What have you been using on your keychain in the meantime?
Statement - You are being way too picky.
Obviously it is you prerogative to go down your own light quest - and I do ultimately wish you success. Maybe you should consider doing what TGWNN did and design and build your own light - in 2 years you would've already had it built exactly as you want it.
