Where To Buy Lasers

Hi,

I am looking to buy a laser diode preferably pressed in a aixiz module, but whenever I look for them they seem to be very expensive. I was wondering if anybody knows a cheaper place to buy?

Thanks!

How long is a piece of string ?

What kind of laser ? What kind of power ?

If you're after a UV laser of around 100mw then you can buy a PHR module out of an old Xbox, remove the laser and press it into a cheap (Dealextreme) host with a LM317 or similar power supply.

Have a look at https://laserpointerforums.com/ for loads of info.
