Best Place To Buy Cheap Labbys

Where is the best place (cheapest price with still respectable quality) to buy strong lab DPSS and Diode lasers? Are these good?

Specifically are these lasers good?

1) 400mW 532nm CNI - $1100

2) 150mW 473nm CNI - $1795

Also, what would be the advantages a 635nm DPSS laser would have over a 635nm diode laser?

DPPS 635nm should have better beam specs than a 635nm diode laser.
Btw those lab lasers do look ok for the price.

I wouldn't say those are very good deals...

What would you say are very good deals because those are by far the best I have found. Some companies don't list prices. Could you post some links to better deals Spyrorocks? Thanks.

Lasershowpart.com is the best quality at competitive prices. I've already searched around looking for better deals and ended up buying from them. A couple other places you can get similar deals are laser-wave and lasever. You might want to consider though that lasershowparts used to sell Laser-wave and have decided to push their CNI lasers. I am guessing this is for quality purposes but who knows. I have also read great reviews about laser-wave. CNI has been well established as a great laser producer and they seem to have it down. Laser-wave is relatively new to the market. Of course you will be able to find cheaper laser but the quality might not be there and they may not perfom at their advertised output. Also when checking prices be sure you are comparing similar products. TTL are usually cheaper than analog. Check for power supplies (OEM or Lab). Check the expected lifetime as well as the length of the warranty. Look at the divergence and beam diameter. Lots of things need to be taken into consideration.

If those indeed are DPSS 635nm (which I doubt) than why do they have "red diode" inside and "multimode" output beam with such bad divergence !
