And those are both what I meant by "Do you have, or are you willing to purchase, the requisite amplifiers that go with this system?" (And then again about subwoofers.)
Wheelin-and-dealin you can probably keep it to about $250k. There's some eBay listings right now for V20/S25 packages, all inclusive, with amps, flybars, and vertical transporters, that could allow someone to step up to the V20s for $125k or less, but keep in mind... you can have the best PA in the world, but if you don't know how to deploy it correctly, it'll sound like shit.
