Any good places to buy a replacement for my t440s from in Austria/France?

Hey peeps! Since my t440s decided to repeatedly not turn on without a hard reset I started thinking about getting a replacement. (Boooh, I only had it for 4 years, I had planned so much for the two of us...) Anyway, I wanted to ask whether you know any good places online where to buy them from? I'm currently doing a PhD in France so student discounts are a possibility. Also I'm in Austria quite often.

I liked the size of the t440s so it shouldn't be bigger than that. I mainly use it for writing, eviews, maybe some light gaming here and there like pillars of eternity or nethack.

Any ideas what I should get? Budget is around 1000 euros max I guess but I'd rather buy some used one for much less if there is some kind of warranty and it's not worse than my old t440s.
