Hmm. Of course, the Pucks come with dongles, but yeah. $25 ain't bad at all. I didn't consider the better battery life though.

Ah. Someone with experience with almost this exact setup. Perfect. 
So, these $25 dollar ones don't have to be modded like the Steam Controller dongles do, right? 
If that's the case, $75 for FBT doesn't sound too bad to me, even if that means that I have to make some custom straps for these wands for my feet and hip. Might be a fun arts n' crafts project.

Thank you for actually answering my question, both of you. You're swell.

One more question, though: I actually got 4 extra controllers instead of 3. Can I, like, do hyper-advanced hip tracking or something with this extra controller, or is it stuck just being a backup?
