Although it's a little more expensive, the Manafont version is 3 mode, no blinkies, with a SS switch. Mine doesn't tailstand however...I've never taken it apart to see if anything can be done with it. But it's a great little light, especially when coupled with a Fenix pocket clip.
I was able to fit a protected trustfire 14500 in mine, and then the LED went PooF about 30 seconds later. They insist at DX that that wont happen any more though, the factory "fixed it".
The original 93mm one (I got mine from DX when they were announced some years ago) I have has worked with every sort of AA I've ever thrown at it, including all the protected ones I have (Which includes flame Trustfires). It does, however, get horribly hot on high with 14500s and more so with IMR cells. I have a pretty high heat tolerance and am not able to hand-hold it for more than 5 minutes on high with a 14500. About 3 minutes with an IMR cell.
DX had both versions at different times 93 and 98mm ... it seems that they are now shipping the 98mm ones. I would go with LT or BOB and ask upfront if that's really the 93mm version.
