Which player to buy in Italy

[Dirac]

Hi to everyone, i'm new.
I'm writing from Italy.
Of course i'm in searching for an mp3 player and after some searching i'm here.
For what i read i think that rockbox have the functionality i'm searching for.
What i need is just a player that after you click the power button it starts to play my mp3 audiobook from the position -20s back where i left off last time.

Can you help me? 
Which player can i buy today (in italy) that is compatible with rockbox or is able to do what i need?

I really appreciate your help

Thank you very much to all
