Even if it equaled the K3 performance, it would be outstanding.
But the problem is and remains Xtal Filters.
We'll need 6, maybe 8 of them and we'll be lucky if they are priced under
$100 each.

If the Corsair III ended up equaling or exceeding the K3S in performance
with the body of an Omni VI+, I'd buy one.
