Price wise you can expect anywhere between $2000 on a good day to $10,000. The difference I would say is pretty huge. A lot of the price difference will depend on a combination of size, features, condition etc.... In general all of those desks will give you between 16 and 24 busses, MUCH better sounding preamps than the budget mixers, MUCH better sounding EQ's than the budget consoles, sometimes some automation, better headroom, better summing, more routing etc.... Having a solid desk as your centerpiece is a really nice option. In my opinion, a good console is the most cost effective way to make sure that everything you record gets a a good quality signal path. Consoles like the one I mention will sound at least as good, and almost always better (in my opinion) than all of your more expensive entry level channel strips like the Focusrite platinum series, presonus channel strips etc... For example, an Amek Big. Certainly not the best sounding AMEK console, but can be had for around $5000 for a 32 preamp, 64 input console with 24 busses and built in patchbay. That would be less than $200 a channel, but sound better than most all of the $600 a channel strips available on the market. With the Amek you can also add different automation packages for recall, moving faders, dynamics etc... The Soundcraft 6000 should run even less than that, but does not have the automation possibilities as easily as the Amek, but in my opinion sounds better. A D&R Orion would be about the same price as a big, but sounds much better than both the Big and the Soundcraft, but is a transparent type sound which not everyones wants or needs. D&R's are harder to find though. They are not as common in the US, and most owners do not want to sell them. The Tridents are excellent rock'n'roll consoles. They have a good fat sound, not as many features, but highly respected. The Tridents I listed are not as nice as a Series 80 or "A" range, but don't cost nearly as much either. In any event, if you are recording bands, then I do not think you would regret the purchase, and it will go much farther than the same money spent on outboard.
