Welcome to Geekhack!
Yes, that is a great deal! I recall a time, not so long ago, then 23UB was rarer than hen's teeth, and someone here was so desperate to get one that they were offering a small collection of artisan keycaps just in exchange for information leading to a purchase!
So you're a Topre fan, eh? Nice
Feel free to post your pictures in the

Btw I got my 2011-02 HHKB (white) for AUD$180 + shipping (around AUD$200 total) shipped a couple of years ago
In near perfect condition, but minus box, and with a little shine on the space bar. I subsequently replaced the space bar with a PBT one.
