Well - I found their shopping site - http://www.sortimo-shop.de/
The basic T-BOXX (just the box, no divider bins):

...costs 27.97 EUR, which is equal to (currently) $34.21 USD. With bins, things jump to 43.44 EUR ($53.14 USD). The cabinet that Adam was using? I have no idea, but Sortimo has to offer it; it looked like it held 28 or 30 of the boxes - let's call it 30 (28 in the cabinet, plus the two extra on top).
That means that sorting solution runs about $1600.00 USD; the cabinet to store the boxes likely is at least another $250-500.00 USD on top. You could probably call it a $2000.00 USD storage system, in total.
I guess I won't be getting one any time soon, unfortunately...sigh.
