Unicomp Ultra Classic Model M Black Spring Keyboard US APL Layout 2017 "Like new, open box", $89.95 or Make Offer + free US shipping
So if the seller accepts, like, $70, it's a pretty nice deal on an otherwise
$87 USB Ultra Classic with a
$35 APL key set (for which you'd also have to pay shipping). You might also want to ask them if they wouldn't mind throwing in the original keys (which, unless they're a real KB geek, they'd have no use for).
Of course it's entirely possible someone here at GH is the seller, in which case they probably won't appreciate my suggesting you offer $20 less—but I
am drawing attention to their sale, so my conscience is clear. Plus, I got to type a long dash just now. Woo hoo.
