Thank you guys for warm welcome and for advice. Now I am hesitating between HQ Jive III and Prism Quantum both are little bit above my price range but if they are worth the money I am ok with that. Parameters seems to me very similar (wind range, size) so if you think one is significantly better than other I'll stick with that.
I have no problem with used kite but community in Czech Republic seems to me quite small so it might take a lot of time to get one or to attend kite event.
