Advice on Cam Belt

Hi,

I am thinking of buying a 2001 Fiesta 1.3 encore and was wondering if anyone knew how much it would cost to get the cam belt changed! How often does this need to be done! I'd be very grateful if anyone could help me out.
Cheers.

Is it true that a 2001 1.3 engine will have a HSC and not a cam belt so will not need changing! any help will be really grateful. PLEASE!!!!!!!
