Should I post a link to this content or not?

in this thread, I asked a question about the effectiveness of ultrasonic weapons I have seen offered on the net.
Would a link to a web page selling them be deemed inappropriate? (the rest of the site appears to be devoted to nothing more than gadgets and ‘boys toys’).

Offhand I don’t see a problem with it, it’s nothing illegal, is it?

Not that THAT’s stopped discussion before.
