Probably the 3 main ones are the Zebralight SC5 (already mentioned), the L3 Illumination L11C, and the EagleTac D25A Titanium Nichia 219, 2015 edition.
The L11C is a really inexpensive and reasonably good quality Nichia 219 light... I have one and it's held up fine so far with the limited use I've given it so far.
The one I'm really interested in, though, is the "kickstarter project" high CRI stainless tritium vial light. There's a thread on it in this forum here:

He's still making design changes and it's still in the prototype stages not yet for sale, but it looks like it will end up being a GREAT light if he follows through and doesn't compromise too much on the design!
