I got a nice hydrometer, range 1.20-1.42 for less than $12 US from:

They were easy to do business with, and shipped to Canada no problem,
I am sure they could mail one to Europe.

Edmund Scientific had a nice cheap pan balance with weights, case, for
$15.00 Canadian; it was made in India, and appears quite accurate
using various canadian coins a reference weights (these are publsihed
on Can mont website)
