You kinda get what you pay for...I am not proficient with such toolsets at present, but I guess it is time to learn. I am presently using 5 channels (inputs - but not at once), so I guess the next step up from 4 is at least 8. The second SOundcraft fits the bill. Any other suggestions closer to $ 200, or do you get what you pay for?
That Soundcraft has a PFL function for accurate level setting, multiple aux sends for external fx etc., per channel muting, on board fx, 6 mic preamps...just lots of traditionally good features.
The Mackie does have inserts though...nice to have if you plan on any insert fx ever...like a nice compressor.
