Socks kniting machines price inquiry from Serbia

Hallo,
I want to buy 5-10 socks kniting maachines, San GIacomo 6CUS,or Fantasia.
Now I have 5 machines San Giacomo 5cus, but I want something better because I think it is old machines.
I need machine 3,3/4 with 120-2oo needles, and I need one machine for winter socks.
So, do you have machines like that, and what is price for them. As you see my Englis is not so good, but I hope you are understand me.
