I've always been partial to soundcraft, and the http://www.soundcraft.com/products/product.aspx?pid=131 looks like a really nice console. I like the sound of soundcraft. There is a sale on the crest at soundbroker.com For Sale - CREST AUDIO HP 840 - 40 CHANNEL X 8 BUSS WITH 10 AUX 5STEREO 4 BAND EQ - Listing Detail - SoundBroker.com Call Jan Landy there. Never liked crest though.
Allen & Heath GL3800/40, looks nice too but my pick of your 3 is SoundCraft only because I like them for live sound.
