Re: Digital mixer - pros and cons?
it sounds like you've got a pretty good handle on where they are. but i still think that you're dealing with a case of 'expectation creep' and at some point there is going to need to be a change of how things are done in order to meet those expectations.
'expectation creep' is actually totally normal and happens in just about every fixed performance space, especially churches where the music program is growing and improving. of course the problem is that usually we can continue to be able to provide every small increase in expectation without any significant change in method or equipment, until it gets to a critical juncture. then we suddenly 'need' a whole new monitor rig or what have you and the non-tech folks can't understand why we would need all this extra stuff to just do this one more little thing. but truth is, if expectations are rising, this point will ALWAYS be reached eventually. of course, with cash strapped organizations like churches this tipping point usually occurs about half a dozen 'expectation increases' later than it probably should.
i think this church is hitting this tipping point. it's entirely possible that their current requests can be met with just another console and some different mixing techniques. but eventually someone is going to want another mix. or someone's gonna want in-ears on top of their wedge. or something. and then they're just gonna have to bite the bullet and change something fairly dramatically.
of course, if i was in your shoes i'm not sure i would want to be the one to try to force that issue. you would like to have their repeat business after all. but then again... if you get their repeat business you're gonna be stuck pushing the same point later...
and that is why i never did consulting for churches... 
good luck and God speed...
