Marantz too pricey.
Zoom H4 nice but still beyond our budget.
Will be recording direct from the record send on the pa so don't need microphones, just some audio in connectors.
So am I missing something Chris but what's the problem with the Ikey then?

As far as I can tell it has no storage and is just an interface to any usb based file system. Having everything in one package will make it easier to use for the non-technical amongst us.
