The D3AA is a great little light. Just a bit chunky..
also consider the upcoming KR1AA discussed here, Im just waiting for V2, due out any day now.
KR1AA is a smoother, more slenderized sibling of the D3AA (same great AA/14500 driver w NoPWM):

yes, POVD is a bit overwhelming at first.. will be glad to help answer any questions when the time comes
