Which of these 3 Lasers should I buy..?

[DeathSimpl]

1W 445nm blue Laser torch/waterproof/focusable [OL445T-1W] - $189.99 : Welcome to O-Like.com, Your source for laser products

www.rayfoss.com

or this one Spartan Series 1W Blue Handheld Laser, Rectangle Beam :: Blue Handheld Laser ----- 447nm Laser ----- Spartan Series Lasers :: Handheld Lasers :: Dragon Lasers

.. and why would that one be better than the others :thinking:

It would be better making your own 445nm laser. It is very easy and it will cost you about 120$. If you want to buy it ready, I would suggest dragon lasers but there is not much difference from building it. Jayrob sells kits and flashlights with drivers and ready heatsink and daguin diodes. Also making your own, will be more powerfull as dragonlasers has the laser fixed focus and o like at low corrent. You decide..

The Spartan is the best out of all of them quality wise. You can DIY one cheaper is in come cases better. There are also some members who sell them in the bst section. DTR makes does a good job. I have one of his >500mw 12x 405nm. He gave me good deal on it.
