Where are the side-printed POM from?
Dante asked the same thing, so I hope he doesn't mind if I'm lazy and cut and paste the answer again.
I got them from aliexpress.com from a seller called EZ Mandarin Shoppers. Here is the link:
http://www.aliexpress.com/item/new-2014-keycool-104-white-PBT-keycap-cherry-mx-mechanical-keyboard-black-POM-side-print/1911069290.htmlNote, I specifically told the seller in the notes I wanted POM with side print, so there would be no mistakes (he also has gray and white PBT in top and side print as well as blank). They cost $39.98 with shipping, only $15 less than my "Ebay-special" keyboard, but I *really* wanted side-printed POM.
From purchase to delivery took about 3 1/2 weeks (4/26 to 5/20). They seem well-made, and I really like the feel.
One cautionary note: they grip Cherry MX stems TIGHT! Changing keycaps from my test keyboard to the Das Keyboard was quite a chore, though on the plus side, I found an easy way to pop the top of Cherry stems to change springs.
Just something to note if you swap keycaps -- if you put them on a keyboard and keep them there, you'll be fine. The only things that didn't fit on the Das Keyboard/Cherry MX 3000 were the capslock (Cherry had a single stem/step design, rather than switch and stabilizer) and the space bar (the Cherry switch is off-center on the Das compared to the one I purchased), but the originals are fine in those position, though a little lower in profile than the one bought from AliExpress.
Finally, Dante did point out the picture on the page is slightly different than what I received -- the website picture shows media symbols (volume and the like) on the function keys, while I just received basic function keys. Still, I rather like them.
