I fear only that there is no way to repay the debt. And, you gave-up the 4313B's, too. Whoa...
Hey - didja notice that 4345 specs the 2421B? Ha! Reminds of a long ago posting exchange...
AND, that 4313B specs the "Midrange chamber"!! Timing, couldn't be more perfect for knowing that - luckily, the router is idle, waiting on that very decision...
Too bad there's nothing like it for the 43xx-series Babies, the 4301B. Oh well...
