Rayfoss Laser Module 50mW

[Gunnishlaser]

OK,
I live in Australia so I'm trying to find some cheap laser modules and lab lasers.
I found this laser module http://www.rayfoss.com/productn.asp?ArticleID=94 on rayfoss.
Is it a good laser and why is it so cheap ?
Even if it is good, I would just like to know where to buy a cheap lab laser (but not really crappy),
probably 50mW. Wavelength does not matter but I'd like red, green or blue.

Please help :na:

It would be helpful if someone actually commented.

The module will provide a decent red diode and AC power supply for DIY laser projects. You chose a line effect module.

If you want just a red diode alone there are higher output choices for much less money out there. Enter search terms "red diode" or "660nm" in the forum search feature.
