I'm really curious about this -

I've noticed the Behringer MDX4600 has secured quite a bit of popularity in the Podcasting Community, and I'm not sure why. Is it because it's cheap? Sure, you get 4 channels of dynamics processing, albeit very basic control options.

I get that flexibility is a good thing. OTOH how many producers would actually need 4 processing channels? To be honest I wouldn't be comfortable recommending that piece.

I have a good amount of past experience with the now discontinued dbx 266xl Compressor/Gate. I would be much more comfortable recommending 1 or 2 of the up to date dbx 166xs two channel processors as opposed to the Behringer.
