Are you looking at the "normal" Aura models? There is an "Aura HD" model, which is older and slightly larger (6.8" instead of 6"), and I feel it is inferior than the newer, "normal" Aura.
Hmm, no, I checked the link and it is the normal Aura. Odd!
Okay, I checked, and it seems they raised the praise by €5 since last week:
here. (It has free shipping in Germany, the one I bought cost €4.99 for shipping, so effectively €5 difference.) You could try and call up a Saturn near you and tell them about the eBay price; perhaps they will match it.) They don't ship to Belgium, though.
Comtech also sell them for €99,
see here.
The information about the price reduction to €99 was
announced here (German text only).
edit: If you can get it locally for €111, I think that is still a fantastic price, by the way. I would have paid more for it and not regretted it. The epub alternatives in the same price group, like the Shine, are noticeably worse (issues with uneven frontlight, less memory, etc.).
