Well, I only have experience with the Soundcraft Digital 328, but it blows away most other digital mixers. You want to know why? Those famous Soundcraft preamps and EQ everyone talks about.
The preamps, to put it bluntly, rock. They sound very good, have low low noise, and fit amazingly well together. I can't describe how great it is to have 32 channels in a mix and not have to worry about the sound getting muddy.
The EQ section is also top notch, and even though for recording I use plugins, live it sounds pretty much the same. They say it's a "british" sounding EQ, but all I know is that it sounds nice and full, and the top end can have some nice sparkle if you wish.
Now, I'm not sure your exact price range, but I got my 328 for $1850, and I've seen them for less. It sounds like you don't want to spend that much, but from what I've heard and read, the low cost analog boards rival anything Allen & Heath have, and blow Mackie, Yamaha, etc. out of the water. I don't think you could go wrong with a Soundcraft, no matter what the model.
