Thanks Ace82.

In addition to being laser hobby newbie, I'm also a newbie when it comes to forums. I just didn't want to wear out my welcome. :)

I'm skeptical about the divergence improvement. As FrothyChimp said, diameter and divergence are inversely proportional so the diameter should be larger. Also, they are only measuring at 1 meter (5 meters to begin with) which makes me think they are measuring negative divergence (focusing). If that is the case, the reading may not be accurate. A divergence measurement is more accurate when it is taken at greater distance.

If you want a good, reliable laser that you can drag around with you for a decent price, you can get one of the Aires lasers from laserglow.
They have models up to 225mW average. Their 100mW model will probably average higher than 100mW, and will go for about $400. Their duty cycle is much longer than that of other portable lasers. Also you can check out the Hercules series, which is much larger and more expensive, but its built for continuous use.
All their products are high quality and they can hand pick a unit that meets your specifications, if you ask.

I just confirmed what they meant by quoting the divergence specs at 5 meters.

5 meters is the distance at which the beam diameter was measured to determine the divergence. :) Of course!

I feel kinda dumb on not figuring that one out myself :-[

Two comments from a newbie.
1. most people who have rushed me seemed to know that research would steer me away from their product. If I am selling the best car then I know that if you do more research you'll come back and buy it and there is no need for me to push a sale before you left the lot.

2. The 50mw greens from aizix put out around 100mw and are only $70. Just got mine and while the beam is not super super tiny the divergence seems really really small to me. I wouldn't say even a meter at a km but thats just me judging not really measureing. But if you go this route you'll be getting a good deal for sure and youll only be out $70. I am more than pleased with mine.
