Not sure about 'no brainer' π.
The TLB had a speaker and they discontinued it, not sure it needed a reciever to actually make a run tone tho??
As for loads of interest, well only thing I dug up was that youtube vid I posted ages ago, nothing on theirweb site lol
Anyway, each to his own, I cannot see this being a winner, and in an odd way I hope it isn't...... just stick to the old skool stuff a lot of us old gits love about ATTs
