There are single-channel echo cancelers out there that are
much less expensive, but in those situations, you probably
only want a single mic and single speaker in your room (good
only for small venues where one mic is sufficient).
Gentner's GT1524 is closer to $1k for instance. Same deal
with the afore-mentioned Polycom solution...
It might also be worthwhile to look at the BSS soundweb
device. This was recommended to me by an audio consultant
as a possible substitute for a Gentner. I was too cautious
to try it myself, but it appears to have many of the same
features as the AP400 (perhaps for less money?). You can
even design and test your audio configs offline running
their software on your PC.
