I did quite a bit of searching on this not too long ago. It seems that
there's a big gap in price/quality on echo cancellation. You go from
$400 to $2000 without much in between.
At the low end, for less than $500 you can get a speaker phone with
built-in echo cancellation and an interconnect to your PC. ClearOne's
phone does the pc interconnect by default -- from polycom you need to
buy it separately. Total cost is about a dead heat -- Polycom was a bit
cheaper in my case, so that's what I went with.
You then jump up to the dedicated echo cancellation gear plus
microphones, which is in that $2-5k range. Polycom & ClearOne are the
two players, near as I can tell. Polycom bought ASPI recently, and it's
the ASPI products that Polycom's pushing (the Vortex line).
Unfortunately, you need to go through a local vendor in order to get
prices & info, since the polycom/ASPI web page meshing is still under
Here are some useful price links for the low end stuff I was talking
Video interconnet for polycom soundstation (to hook to PC)
I hope this helps!
