Define 'budget' :-)

Gentner/ClearOne have a couple of models, Polycom/ASPI have a larger range and in general I have found them cheaper than the equivalent Gentners (your country may vary :-) ). There's also the CallPort, but I'm not sure if that's been EOL'ed. Then there are companies that have licensed the Gentner and ASPI technologies in their own boxes.

You can go from single-channel EC up to almost any number of channels. With fewer channels you have to do more work mixing the audio inputs, and they become less adaptive to changing room conditions. But for an urgent need, or a small room, they may suffice.
