I have a T20C2 MK II, and I think it's a super nice light. And yea, you're right, they come with some really nice accessories. Their screw in diffuser is extremely nice! One of the things I like about the ET's is the fact that many are upgradeable for cheap, simply by purchasing a new "screw in" module. I have 4 for mine. Makes the light a nice thrower, or a sweet neutral, or just kick butt bright with the high output XM-L. Their 18650 cells are also very good quality, for about half the price of the more popular ones. I have some, and they've never give me anything but great performance. Try one. I honestly don't think you'll be disappointed.
