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.
