Less throw than the C8 and cost a bit more. Some issues with mode change, read the thread and decide for yourself.

D40A group buy price might still be on(?) but that's $50. I ordered one but haven't received it yet.
(You can run a C8 on 4xAA's if you can find extension tubes, but they're rarer than hens' teeth for Ultrafire. FastTech has Convoy tubes, though.)
