These nades require level 175 engineering to make. They also require 175 engineering to use. Therefore, if you're buying the actual grenades for more money than it costs to buy the mats, then you're pretty stupid.
The main reason to vendor them though is that it's a definate profit, whereas the AH will not always be responsive (server dependant). If you can sell the mats for more consistently than these vendor for, for 3x the vendor price, then making these for cash is unnecessary.
