I have seen that company selling on amazon before- That's how I originally found their website- I just did a quick search and it isn't coming up- I wonder if it's just out of stock or something along those lines.
Used this one in 3 rooms of my house, came with a bunch of emitters so I kept em around- god knows I'll be buying more devices!

In my basement theater I rely on an IR repeater as well, this one did the trick quite nicely-

This is the repeater that I used and it works pretty well- nice not having to have everything out in the open!
