I bought some scarts from
www.lektropacks.co.uk.
I can recommend their Home Cinema Scarts at £16 for 1.5m or £13 for 0.75m. Fully wired / multi shielded etc I'm well pleased with the results.
Also bought their switch box (BT23 nb. BT22 not RGB) to connect Cable Digital box and DVD player to the single RGB scart on the TV, again I get perfect results. Even though you have to manually switch it, it's only a case of flicking the switch next to the DVD player - you have to go there to put the disk in anyway!
Final comment on their scarts - I bought a couple of 10m scarts to connect a PC to 2 28" TVs to act like Call Centre wallboards and considering the length of the run, the fact that there are a couple of adapters to get from the PC out vid card to the scart on the TV the results are spot on.
Cheers
