You can always make your own RGB to Scart cable. I built mine using; a normal scart lead from Aldi (£2); a 23-pin D socket, 23 way hood and a couple of resistors from
www.esr.co.uk (approx £2); RCA audio leads from a carboot (50p).
Wiring details can be found on the net, but if you have problems finding them I can email them to you.
