...relatively inexpensive, compact 1xCR123 light. This light would mostly be for sucking the remaining life out of my old 123s.
Flat regulation would be nice. 3 watt LED would be nice. Under $100 would be nice.
All these things are found in the Q3:

Semi regulation as said in Quickbeam's review. I got mine modded by Milkyspit, he changed the driver to a DorcyAAA's board, and changed the Luxeon to a TYOH, and it's runtime is unbelieveable. On a "dead cell", it still ran for about 8 hours of usable light.
Also, if you can manage to find a AA extender tube for it (I got a 1xAA tube from a CPF'er), I had a "dead AA" (would not power a discman) run for about 10+ hours.
But a stock Q3 would be great too. I only say the Q3 over the Dorcy Super 1W CR123, because
#1 I own a Q3 and Q1, but not a Dorcy 1W
#2 The Q3 and Q1 come with clips(which are a selling point for me) and holster.
Too bad you missed the groupbuy for the Ilumibeam Ulteon X-1, that's a great little light at a even better price. And it came with a nice holster.
Those HDS's ain't so inexpensive to me! But you may want to save your pennies for one of those, that's what I was doing until I got the Q3 and had it upgraded. Almost ends up costing the same with all the modifications done, too.
Talk to brunner, he's another lover of "all things single cell". He would be very insightful, I'm sure.
I sorta surprised he hasn't chimed in yet...
