YES! I have a Maratac Stainless Steel AA! My new current EDC light. I had never owned a twisty until I got a Quark Mini 123 with the new XM-L LED a few months back. Never really knew twistys existed till I joined CPF. They looked interesting, so I got one. The different levels of light is a useful feature, especially the low when moving about at night and trying to maintain low light adapted vision. As much as I really liked the Quark Mini, I wanted something in silver. Titanium I would need to save up for, but the stainless steel was definitely affordable. The Maratac has tighter threads than the Quark Mini, which I have come to appreciate, and the AA form factor makes it very easy to supply. I use Energizer Lithium's in mine, which I buy when they are on sale locally.
