Hi everyone! I just wanted to let you all know, what I finally came up with. As availability of the ClearOne AccuMic PC is very rare and is not produced anymore (according to my national reseller) I decided for a solution which is in the beginning a bit more work. I ended up buying the following DSP-EchoCanceler-Board
http://www.phnxaudio.com/Default.aspx?tabid=75 Basically it does the same as their PCI-Card which however only fits in Desktop-PCs. (see link for information: http://www.accessgrid.org/node/116) In addition to the board I bought some stuff to put everything in a small case and have 3.5mm (like they are common among PCs) connectors in that case. The result is a small echo canceler device that is portable can be used with PCs and Laptops and in conjunction with small audio mixers like from Behringer it can echo cancel a tabletop and a wireless mic. The whole cost only was about 180Euro for the complete box. Fields of application for us will be, to quickly equip rooms with AccessGrid in conjunction with a table top microphone for conferences up to a max. of ~10 people. Furthermore usage on exhibitions in conjunctions with wireless mics, AccessGrid and our collaborative software is intended. I consider that cheap and more flexible even compared to the ClearOne AccuMic PC which in Germany was around 650 Euro. So that's my 2 cent. I might post an entry in AccessGrid.org's hardware section, however I am not sure whether that would be of use as you can't buy that box but only the parts to assemble it.
