Here's a link for those of you in Germany (or all of EU?) who want to buy one:
It's not totally clear from the description, but since there is no mention of SO, the devices are likely to be regular (non-SO) ones. I had bought my current Kindle Touch (with SO, and that was clearly stated) from Mexxbooks in November 2011 without much trouble (except for a rather long wait for it to be shipped because of capacity issues), so I personally recommend them. And the prices are fair.
There are no strings attached, except that you agree that they may send you a weekly newsletter for the duration of one year (though I never received one
). This is not a huge company, but rather a bunch of enthusiasts, so I don't know how well they can cater for non-german speaking folks, or whether they ship to other countries. It's probably easiest to just send them an e-mail and ask.
Note that the offer is currently limited until tomorrow, September 15
(or as long as "supplies" last, whichever comes first).
