Well, to give credit where credit is due, those articles were found by someone on photonlexicon. I have had my own personal horror story with them, and considering all of their items are oversensationalized, with little useful information to them, they seem more like a Spymode-type company to me.
If you want an IR module, I believe AixiZ has some good deals on similar modules. I also have some 260mW IR diodes for sale for ~$10 apiece + shipping, but of course for the price difference between the diode and the model, you get a nice, solid laser module instead of a bare diode.
